Why Michigan's Senate race and Proposals 1 and 2 matter on Election Night

Michigan voters are deciding an open U.S. Senate seat and weighing two statewide ballot questions with consequences that reach well beyond one campaign cycle. The Senate contest pits Democrat Abdul El-Sayed against Republican Mike Rogers for the seat being vacated by Democratic Sen. Gary Peters, while Proposal 1 asks whether Michigan should hold a constitutional convention and Proposal 2 would tighten some rules around political contributions and disclosure. This is one of the highest-profile races on the state ballot, and it is unfolding alongside a governor's race, House contests and fights for control of the state Legislature.

The stakes are both national and local. Nationally, the open Senate contest is tied to the broader fight over Senate control. Locally, the two ballot measures could influence how Michigan rewrites — or declines to rewrite — the rules of state government and how money moves through state politics. And because some Upper Peninsula counties in the Central time zone keep polls open until 9 p.m. ET, the AP Decision Notes for Michigan say AP will not declare statewide winners before then.

Why is this Senate race getting so much attention?

This is an open seat in a closely divided Senate, which immediately makes Michigan one of the more important races on the map. Peters is retiring after two terms, and Republicans have not won a U.S. Senate race in Michigan since 1994, giving the contest both historical weight and practical importance for either party's path in Washington. The race also drew heavy national involvement, with hundreds of millions of dollars from outside interests and the parties pouring in.

The chamber's current party division is 53 Republicans, 45 Democrats and 2 independents who caucus with Democrats. Because Vice President JD Vance can break ties, Republicans keep control at 50 seats, while Democrats need 51, a net gain of four seats. Michigan is a Democratic-held seat, so Republicans see a flip here as a way to block Democrats' path to a majority; if Republicans win it, Democrats would need five pickups elsewhere to get the net gain of four they need.

Who are the candidates, and what cases have they made?

El-Sayed is a physician and former Detroit public health director who also led the Wayne County health department. He has never held elected office, lost the 2018 Democratic primary for governor to Gretchen Whitmer and lives in Ann Arbor, where he has taught. He narrowly defeated U.S. Rep. Haley Stevens in the Aug. 4 Democratic primary by about 1 point, and if elected he would become the Senate's first Muslim member; progressives including Sen. Bernie Sanders backed him, and former President Barack Obama campaigned for him.

Rogers is an Army veteran and former FBI agent who served 14 years in the U.S. House and chaired the House Intelligence Committee. He narrowly lost Michigan's other Senate seat in 2024 to Democrat Elissa Slotkin by fewer than 20,000 votes and was unopposed in the Republican primary this year. In campaign messaging described by AP, El-Sayed has portrayed Rogers as a rubber stamp for President Donald Trump, while Rogers has argued that El-Sayed is too extreme for the state.

Minor-party candidates also appear on the ballot: Lydia Christensen of the Libertarian Party, Tim Long of the U.S. Taxpayers Party, Douglas Marsh of the Green Party and Walter Kristy of the Natural Law Party. Their presence is a reminder that even in a race dominated by the two major parties, Michigan voters are not limited to those choices. On a ballot that also includes statewide proposals and other major offices, the Senate race sits inside a broader set of decisions about the state's direction.

What changed in the final days of the campaign?

A late development came from Stevens, El-Sayed's former primary rival. On Sunday, Nov. 1, she withdrew her endorsement of El-Sayed and endorsed Rogers, according to AP's account of the switch. Coverage said she cited disagreements with El-Sayed's campaign, including over its messaging.

That move did not alter the ballot, but it added another layer to a race that was already nationally watched. It also drew attention back to El-Sayed's narrow primary win and to the question of coalition-building in a state where statewide contests can be competitive across regions and demographic groups. In practical terms for voters following election night, it became one more reason the race attracted outsized scrutiny, even though the basics of how ballots are counted and winners are declared did not change.

What exactly is Proposal 1 asking voters to do?

Proposal 1 asks whether Michigan should hold a constitutional convention, a question that automatically appears on the ballot every 16 years. Voters have rejected it in prior elections, and Michigan last rewrote its constitution more than 60 years ago. That means the measure is not just about one policy dispute; it is about whether to open a process that could revisit wide areas of state law and governance.

If voters approve Proposal 1, partisan primaries would be held to nominate delegates, followed by a general election by mid-2027. There would be 148 delegates, one from each state House district and one from each state Senate district, with no requirement for partisan balance, and the convention would convene in Lansing by Oct. 5, 2027. There is no limit on the convention's length or scope, but voters would still have the final say because any new constitution would have to go back to the statewide electorate at least 90 days after the convention adjourns.

If voters reject Proposal 1, no convention is held and the question returns in 16 years. Opponents, including the politically diverse coalition Protect MI Constitution from Special Interests and Whitmer, argue that special interests could wield too much influence and that delegates could target popular provisions such as the voter-approved abortion-rights amendment. Supporters say a convention could provide a way around partisan gridlock and create room to address issues including data centers and property taxes.

What would Proposal 2 change about political money and disclosure?

Proposal 2 focuses on political contributions and transparency rules in Michigan elections. It would prohibit direct or indirect contributions to Michigan politicians by utilities regulated by the Michigan Public Service Commission, DTE Energy and Consumers Energy, and by companies with more than $250,000 in state government contracts. The proposal would extend those limits to company officials, immediate family members and people with substantial ownership stakes or board seats.

The measure also would require groups running issue ads that mention a candidate or ballot issue within 100 days of a general election or 30 days before a primary to disclose donors and expenses. At the same time, it would not ban independent-expenditure super PAC contributions allowed under Citizens United, and it includes a severability clause. Michigan law already bars corporations from contributing directly to candidates, so Proposal 2 is best understood as expanding some restrictions and disclosure requirements rather than creating an entirely new campaign-finance system from scratch.

Supporters, including Michiganders for Money out of Politics and Obama, say the proposal would curb pay-to-play politics. Opponents argue it would restrict free speech, and Bridge Michigan reports they are likely to sue if it passes. That makes Proposal 2 consequential not only for donors and campaigns, but also for what future court fights over the measure could look like.

When do polls close, and why can a statewide call wait?

Most of Michigan closes its polls at 8 p.m. local time, which is 8 p.m. ET for the bulk of the state. But some Upper Peninsula counties are in the Central time zone, so their polls close at 8 p.m. local time there, which is 9 p.m. ET. That is why the AP Decision Notes say AP will not declare statewide winners before 9 p.m. ET.

That timing rule matters because statewide races cannot be fairly settled before every part of the state has finished voting. It also helps explain why readers should not assume that a quiet first hour means anything unusual, or that an early trickle of updates reflects the whole state. AP's standard, described in its explanation of how AP calls races, is to declare a winner only when it determines there is no scenario in which the trailing candidate can close the gap.

Why might the counting pattern look uneven at first?

Michigan's process has changed in a way that can speed the handling of absentee ballots but does not make every county report at the same pace. A 2023 law lets cities and towns with at least 5,000 people process and tabulate absentee ballots up to eight days before Election Day, while smaller jurisdictions may start the morning before. That means the first updates can contain a mix of absentee ballots, early in-person ballots and Election Day voting rather than a simple one-category snapshot.

Even with that change, the first updates still may not represent the state's largest vote centers proportionally. Big counties including Wayne, Oakland, Macomb, Kent, Genesee and Washtenaw tend to release relatively few results early, so the pattern can look uneven before fuller batches arrive. In 2024, AP first reported Michigan results at 8:06 p.m. ET, reached the halfway mark at 12:12 a.m. ET and posted the last update of the night at 4:40 a.m. ET with about 99% counted, a reminder that the count can keep moving long after polls close.

Another piece of context is how many Michiganders vote before Election Day. About 4.5 million votes were cast in the 2022 governor's race, and about 42% were early in person or by mail. Those habits matter because they shape when ballots are ready for tabulation and how different parts of the count may appear in sequence.

What happens if the margin is very close?

Michigan law provides an automatic recount in statewide races if the margin is 0.1% or less. Candidates also can request and pay for a recount under the 2024 recount law, which means the process for settling a close race does not end simply because election night has passed. In a contest with high national stakes, that legal structure is part of the story readers should keep in mind as they watch for an AP call rather than focusing only on the clock.

For readers checking official information, the Michigan Secretary of State election data page is the state's central hub for election results and data. Readers who want a national media overview can also follow the NBC News Michigan Senate results page using AP data. And while the Senate race and Proposals 1 and 2 are major focal points, voters also are choosing a governor in the contest between Democrat Jocelyn Benson and Republican John James, along with House members and state legislators, all of which helps explain why Michigan is getting so much national attention tonight.
