Michigan’s Senate Race Is a Referendum. The Question Is on Whom.

Sep. 21, 2026 · Lance Lunsford

The closest Senate race in the country turns on one question: will an angry Democratic base show up against President Trump when it doesn’t much like its own party?

Michigan’s open Senate seat, vacated by retiring Democrat Gary Peters, is a genuine coin flip. Democrat Abdul El-Sayed leads Republican Mike Rogers in most September polls, but only one gives him more than a margin-of-error edge.

Cook, Sabato’s Crystal Ball, and Inside Elections all rate it a Tossup. Schumer-aligned Senate Majority PAC has put $30 million into the state. The GOP’s Senate Leadership Fund has committed $51 million, and a MAGA-aligned super PAC plans another $18 million.

El-Sayed says “All pathways to a Senate majority run through Michigan.” Chuck Schumer is hedging, however, to recognize the critical time to win over voters and convince them in other states that his party has solutions: “A path… clearly goes through Michigan, but we have a whole bunch of different paths,” Schumer said.

The national environment certainly seems to favor Democrats. Yet, Michigan is close anyway. That gap highlights a deeper story both sides seem hesitant to explore deeply, reaching instead for superficial grab bag of over-simplified political talking points that make memes and two-frame gifs look like complex political rubrics.

Referendum #1: Donald Trump

Midterms usually become a vote on the sitting president, and Michigan fits that pattern in three ways.

1. Trump is underwater in a state he won. Trump carried Michigan in 2024. Emerson now puts his approval there at 40% approve, 55% disapprove. Nationally, Marquette Law School has him at 37/63, with strong approval down to 15% from 29% in February 2025.

2. Rogers tests Trump’s coalition without Trump on the ballot. In 2024, Rogers lost to Elissa Slotkin by 19,006 votes, about a third of a point, even as Trump carried the state. The question for 2026 is whether Trump’s voters come out for Rogers when Trump isn’t on the ballot. Suffolk’s poll suggests a warning sign: independents favor El-Sayed 51–35.

3. The economy now belongs to Trump. Emerson found 47% of Michigan voters rank the economy first in priorities, far ahead of health care at 13%. Suffolk director David Paleologos says dissatisfaction with tariffs and data centers “caused a massive shift to Democratic candidates among independents.” In an automotive state, every price complaint might reveal itself as a verdict on the White House.

Referendums #2 and #3: The Democratic establishment, and the candidate himself

The party establishment. El-Sayed beat Rep. Haley Stevens, the establishment favorite, by less than a point in August: 48.5% to 47.6%. More than 1.2 million people voted in that Democratic primary, up from about 933,000 in 2024, per Bridge Michigan. El-Sayed took more than 60% in Kent and Washtenaw counties. Stevens swept metro Detroit and won more than 60% in Detroit itself.

El-Sayed has stayed noncommittal about backing Schumer as Democratic leader — another telling feature of emerging candidates and the intensifying purity tests applied in several state primary races. If he wins, a progressive who owes party leadership very little goes to the Senate with chips to cash in for voters but potential for relationship struggles if established leaders are at the helm. If he loses, the establishment will say it warned everyone.

The candidate. The Washington Post–Schar poll finds El-Sayed running behind the environment his party is enjoying. It reports that more than 4 in 10 likely Michigan voters say they would not support a Muslim candidate for president, and that those attitudes go along with lower support for El-Sayed. There is also an education divide. Emerson has voters without a four-year degree favoring Rogers 48–45, while college graduates favor El-Sayed 53–42.

Independent TJ Stephens is also on the ballot. Suffolk measured minor candidates at 3% combined, which is enough to play a notable role in a race this close.

The Democrats’ mobilization problem

Rogers’s best path is Democratic voters who are fed up with their own party. The data shows that frustration clearly, and it has lasted for months.

  • Now: Only 36% of Democrats approve of how Democrats in Congress are handling their job, and 64% disapprove (Marquette Law School, Sept. 2–9, 2026).
  • The slide began earlier: Democrats’ favorable view of their own congressional members fell from 85% in November 2024 to 63% in January 2026 (Economist/YouGov). YouGov noted that net favorability “has fallen to +30 from +51 over the past month.”
  • The quote that sums it up: When Quinnipiac found congressional Democrats at a record-low 18% approval in December 2025, analyst Tim Malloy said: “Democratic voters want their party to hold the reins of the House but are not the least bit happy about what they are doing at the moment.”

What matters on Election Day. Unhappy voters rarely switch parties. They stay home, and Michigan is decided by thin margins. The Washington Post–Schar poll shows where the risk is: 83% of likely Black voters want Democrats to control the Senate, but only 67% back El-Sayed. Detroit went for Stevens by more than 60% in August. If El-Sayed can’t close that 16-point gap in Wayne County, the national environment may not be enough to carry him.

The case against the worry. Marquette finds 47% of Democrats “very enthusiastic” about voting, compared with 32% of Republicans, and Democrats lead the national generic ballot among likely voters 54–41. In the primary, El-Sayed won 59% of Election Day voters in Wayne, Oakland and Macomb, which suggests he can bring out new voters. Being angry at your party and skipping the election are two different things.

The bottom line

Michigan will measure which is stronger in 2026: anger at Trump, or Democrats’ frustration with their own party. If anger at Trump wins, El-Sayed wins, and Democrats have a real path to the Senate majority. If frustration keeps enough Democrats home in Detroit, Rogers wins the seat he missed by 19,006 votes two years ago.

Is Michigan voting on Trump, or on the Democrats?

Trump is underwater in Michigan, at 40% approve and 55% disapprove, and Democrats lead the national generic ballot by double digits. Even so, Abdul El-Sayed vs. Mike Rogers is a coin flip.

The reason is that Democratic voters aren’t happy with their own party. Only 36% approve of how congressional Democrats are doing their job. And in Detroit, which went heavily for Haley Stevens in the August primary, El-Sayed still has ground to make up.
