Recent Developments (Entry Point for Updates)

• September 2, 2026: A bipartisan legislative oversight committee (the State Administration and Veterans Affairs interim committee) voted 10-1 to subpoena Secretary of State Christi Jacobsen, demanding a list of exactly what categories of Montana voter data her office turned over to the U.S. Department of Justice. Lawmakers from both parties say Jacobsen has repeatedly declined to disclose this despite direct questions. Context: Jacobsen entered an agreement in November 2025 to run Montana’s voter rolls through DHS’s SAVE database and spent $196,000 in federal grant money on postcards featuring her and President Trump promoting the effort; the SAVE search identified 23 potential noncitizen registrations out of roughly 800,000 registered voters.
• Montana was not sued by DOJ over its voter rolls. Montana is one of two states (with Kansas) that DOJ has publicly credited as “cooperating” by providing voter-list data without litigation. But “cooperating” is doing real work in that sentence: the subpoena above exists precisely because state lawmakers don’t yet know the full scope of what was shared, or whether it went beyond what DOJ obtained elsewhere through litigation.
• Montana has same-day registration, and two attempts to end it have failed. A 2021 law (HB 176) ending Election Day registration was permanently enjoined by a district court in 2022 and struck down by the Montana Supreme Court in March 2024 as an unconstitutional burden on Native American and young voters. The 2025 Legislature tried again with Senate Bill 490, tightening the cutoff to noon the day before Election Day; a Lewis and Clark County district judge (Adam Larsen) preliminarily enjoined SB 490 on May 11, 2026, and as of this writing Election Day registration remains open in person at your county election office through the close of polls (8 p.m.) on Election Day. This is a preliminary injunction, not a final ruling — track it through November.
• Student IDs are accepted Montana voter identification. A companion 2025 law, Senate Bill 276, updated Montana’s voter ID requirements and now explicitly lists student ID cards, tribal photo ID cards, Montana concealed-carry permits, military IDs, U.S. passports, driver’s licenses, and Montana state ID cards as acceptable — and it was not blocked by the same court challenge; Judge Larsen left it in place, finding no eligible voter had yet been denied a ballot under it. Voters without any of those forms can still show a utility bill, bank statement, paycheck, or government document listing their address.
• Montana’s third-party ballot-collection restriction was struck down, and the bill number was HB 530. The actual 2021 law restricting third-party ballot collection was House Bill 530, and it was permanently enjoined by a district court in 2022 and struck down by the Montana Supreme Court in the same March 2024 ruling that restored Election Day registration (Western Native Voice v. Jacobsen). Paid ballot collection assistance — which reservation communities disproportionately rely on — is not currently restricted by that 2021 law.
• A separate 2025 law, House Bill 413, redefined residency to bar college students in Montana “for temporary work, training, or an educational program” from registering to vote locally unless they commit to staying permanently. A district judge (Jason Marks) issued a temporary injunction against HB 413 in early 2026, finding it likely unconstitutional; that too remains pending, not final.
• September 4–7, 2026 (federal): Judge Indira Talwani (D. Mass.) issued a September 4 preliminary injunction blocking the USPS mail-ballot rule (EO 14399) through the November election — the order that currently controls; the June 25 injunction was vacated August 26. DOJ has asked the Supreme Court to stay the September 4 order; that application is pending. Montana is one of 12 Republican-led states that formally intervened to support the Trump administration in this litigation. Separately, Montana joined an amicus brief with eight other states in the Supreme Court’s Watson v. RNC case, arguing against mail-ballot grace periods; the Court ultimately ruled in June 2026 that states may choose to keep them, but Montana’s own law has no such grace period regardless.
• Montana’s U.S. Senate seat is open for the first time in a decade. Sen. Steve Daines (R) withdrew his re-election bid minutes before the March 2026 filing deadline. The November 3 general election ballot features Kurt Alme (R, Trump- and Daines-endorsed), Alani Bankhead (D), Seth Bodnar (I), and Kyle Austin (L).

State Threat Profile

Montana’s Legislature has tried twice, since 2021, to roll back Election Day voter registration and once to restrict third-party ballot collection — restrictions that fall hardest on Native American communities on reservations where the nearest post office or county election office can be dozens of miles away. Both of the 2021 laws lost in court, permanently. The 2025 Legislature’s renewed attempt at a same-day-registration cutoff (SB 490) is also currently blocked, but only by a preliminary injunction — a real, live distinction from the 2021 laws’ permanent, final defeat. A parallel 2025 law targeting college-student voter eligibility (HB 413) is in the same preliminary posture. Track both closely; either could be narrowed, reversed, or affirmed before November 3.

Layered on top of that recurring fight over registration access is a live transparency dispute: Secretary of State Christi Jacobsen’s office has shared Montana voter data with DOJ and, separately, run the state’s rolls through DHS’s SAVE database, but has resisted a bipartisan legislative committee’s direct requests to specify exactly what was shared — hence September’s subpoena. Montana avoided a DOJ lawsuit by cooperating, but cooperation without disclosure is its own accountability gap.

Montana’s rural geography means USPS reliability is not an abstract concern here the way it might be elsewhere — for many reservation and frontier communities, mail is the only realistic way to receive and return a ballot, and drop boxes and county election offices can be a long drive away.

Primary threat vectors:

1. SB 490 (2025) — a renewed attempt to cut off Election Day registration at noon the day before, currently blocked by a preliminary (not final) injunction
2. HB 413 (2025) — a residency redefinition that could bar temporarily-present college students from registering locally, currently blocked by a preliminary (not final) injunction
3. Unresolved scope of the Secretary of State’s voter-data sharing with DOJ and use of the SAVE database — now under bipartisan legislative subpoena
4. USPS/mail reliability in rural and reservation areas, combined with Montana’s own intervenor posture in the federal USPS mail-ballot litigation
5. Montana’s federal delegation and state leadership are uniformly Republican for the first time since 2025, removing a divided-government check

Primary protections already in place:

1. Election Day registration — permanently upheld by the Montana Supreme Court (2024) against the 2021 law, and currently preserved against the 2025 law by a preliminary injunction
2. Third-party ballot collection assistance — permanently unrestricted since the Montana Supreme Court struck down HB 530 in 2024
3. A broad, court-tested voter ID list that now explicitly includes student IDs and tribal ID cards, plus a non-photo fallback (utility bill, bank statement, paycheck, or government document with an address)

Legal Disruption Routes

Officials in Key Positions

AG Austin Knudsen’s disciplinary status is resolved (not suspended, not “uncertain”) — the Montana Supreme Court declined to suspend him. Sen. Steve Daines remains in office but is retiring, not seeking re-election; do not describe Montana’s Senate race as an incumbent race.

Official Statements on Election Integrity

• SoS Jacobsen called the May 2026 court ruling upholding the voter ID law “a victory for election integrity” and has defended the SAVE database program publicly, while declining the legislative oversight committee’s repeated requests to specify what voter data her office shared with DOJ.
• Sen. Jacinda Morigeau (D), on the subpoena vote: “Our county election administrators across the state do an incredible job maintaining accurate voter rolls. Montana’s Secretary of State should not be in the business of second-guessing them and sending private voter information to the federal government. The federal government overstepped its authority, but this boils down to a simple question: What did the Secretary of State share?”
• Rep. Marc Lee (D), the oversight committee’s vice chair: “We have asked the Secretary of State multiple times to disclose what private information about Montanans was sent to the federal government. We have been rebuffed every time. This action is not taken lightly.”
• Sen. Mike Cuffe (R), sponsor of both SB 490 and SB 276, said his intent with SB 490 was to “smooth out the process and avoid votes being cast many hours beyond the intended closing of the polls,” citing voters who waited until after midnight to register in Gallatin County in 2024.
• ACLU of Montana’s Alex Rate, after the SB 490 injunction: “The State of Montana could not provide a compelling government interest justifying this voter suppression law because there simply isn’t one. Election Day voter registration is secure, it’s fair, and — with this ruling — it continues to be protected in Montana.”
• Tribal nations (Confederated Salish and Kootenai Tribes, Blackfeet Nation, Fort Belknap Indian Community, Northern Cheyenne Tribe) intervened as plaintiffs against SB 490, as they did against the 2021 laws, continuing a now years-long pattern of defending Election Day access in court.

Step-by-Step Defense Playbook

For Every Voter

1. Register at least 30 days before Election Day if you can — the safest option, unaffected by any of the pending litigation. Verify or register at votemt.gov or sosmt.gov/elections.
2. Know the late- and Election-Day options too — Montana law allows registration through a “late registration” period, and, as of this writing, in person at your county election office through the close of polls (8 p.m.) on Election Day itself, because a court has blocked the 2025 law that would have cut this off at noon the day before. Confirm this hasn’t changed by checking with your county election office close to Election Day — this is under active litigation.
3. Check your registration status at MyVoterPageMT.com, especially if you were flagged in any SAVE-database review; if you’re wrongly flagged, contact your county election office immediately — a favorable outcome is not automatic.
4. Bring valid ID — Montana’s accepted list is broad: a Montana driver’s license, Montana state ID card, tribal photo ID card, military ID, U.S. passport, Montana concealed-carry permit, or student ID card, all of which must be current, valid, and readable. If you don’t have one of those, a utility bill, bank statement, paycheck, or other government document showing your current address is an accepted alternative.
5. Request your mail ballot early — Montana runs largely on absentee/mail voting even outside all-mail counties; request as early as possible, and don’t wait if you’re in a reservation or frontier community far from a post office.
6. Use a drop box if your county has one — this avoids USPS delays entirely. Confirm locations with your county election office; not every county offers them.
7. Track your ballot at MyVoterPageMT.com to confirm it was received and accepted. If the status doesn’t say “accepted,” you can still vote provisionally at your polling place to make sure your vote counts.
8. Vote absentee in person if you’re worried about the mail — county election offices process in-person absentee voting well before Election Day; this sidesteps USPS entirely.

For Election Workers

1. Know the Election Day registration rules as they stand right now, not as SB 490 would have written them — full-day availability, subject to change if the litigation resolves before November. Get updated guidance from the Secretary of State’s office close to the election, and don’t rely on materials printed before a court ruling.
2. Know the current voter ID list precisely — including student IDs and concealed-carry permits, which some voters and even some poll materials may not expect to be accepted.
3. Document USPS delivery timelines systematically, especially in reservation and frontier zip codes, to support any future litigation or advocacy.
4. Maintain strict chain of custody, with extra documentation discipline in tribal areas given the history of legal disputes there.
5. Provisional ballot procedures — know them cold; they’re the backstop for any voter caught in the current registration-litigation uncertainty.

For Organizers

1. Correct the record on what’s already been won — same-day registration and third-party ballot collection are not currently restricted in Montana; two 2021 laws that tried to end them were permanently struck down. Don’t discourage voters with outdated information about barriers that no longer exist.
2. But don’t overstate the win either — the 2025 replacement attempts (SB 490 on registration, HB 413 on student residency) are blocked only by preliminary injunctions, not final rulings. Keep monitoring and be ready to update guidance fast if either changes before November 3.
3. Native community coordination — partner with tribal councils (Blackfeet, Crow, Fort Peck, Confederated Salish and Kootenai, Northern Cheyenne, Fort Belknap, Rocky Boy’s) to plan ballot access around the specific geography of each reservation.
4. Student voter mobilization — with SB 276 now explicitly accepting student IDs, and HB 413’s residency restriction currently blocked, temporarily-present students at UM, MSU, and Montana Tech can register locally; make sure this reaches students who may have heard the older, more restrictive version of the rules.
5. Push for transparency on the DOJ data-sharing question — the legislative subpoena of SoS Jacobsen is a live opportunity for public pressure and FOIA-style requests at the state level.
6. USPS monitoring — track mail delivery timelines in rural zip codes; document systemic delays for potential litigation and public advocacy.
7. Cultural competency — voting materials in tribal languages, culturally appropriate outreach, and respect for tribal sovereignty in all coordination.

For Lawyers

1. Monitor the SB 490 and HB 413 appeals closely — both are preliminary injunctions, not final judgments; either could be stayed, narrowed, or affirmed by the Montana Supreme Court before Election Day. A late reversal would need urgent, coordinated voter communication.
2. DOJ/SAVE data-sharing oversight — the legislative subpoena of Jacobsen’s office is a public record worth tracking; consider a parallel state public-records request for the specific data categories shared with DOJ and any MOU governing its use.
3. Redistricting/Callais exposure — Montana was not named among the states newly free to redraw congressional maps after Louisiana v. Callais (April 2026), and its two-district congressional map is unchanged since 2022. The doctrinal shift still matters at the local level: watch county-commission and school-board election systems bordering reservations for any changes that would previously have drawn a Voting Rights Act Section 2 challenge.
4. NVRA 90-day quiet period — active now (began August 5, 2026). Any systematic Montana voter-roll purge activity tied to the SAVE database review during this window deserves scrutiny for NVRA compliance, independent of the state litigation above.
5. HB 530’s permanent injunction is settled law — cite the 2024 Montana Supreme Court ruling directly in any new dispute over ballot-collection assistance; this issue should not need to be relitigated from scratch.
6. Tribal court coordination — some election disputes may involve tribal sovereignty intersections; maintain relationships with tribal legal departments.
