Obama and Trump to campaign in Michigan on back-to-back days in race that could decide the Senate

With nine days left before Michigan voters decide one of the closest Senate races in the country, both parties are sending their biggest surrogates into the state on consecutive days. Former President Barack Obama appears in Detroit on Saturday with Democratic Senate nominee Abdul El-Sayed and gubernatorial nominee Jocelyn Benson, and President Trump follows on Sunday with a rally in Port Huron for Republican Senate nominee Mike Rogers, a city St. Clair County officials say has never before hosted a sitting president.

The split-screen arrives as early in-person voting opens statewide on Saturday, Oct. 24, under a voting window Michigan voters created by constitutional amendment in 2022, and runs through Nov. 1 ahead of the Nov. 3 general election. The Michigan Secretary of State's office reported on Oct. 13 that roughly 6 percent of active registered voters had already cast ballots, with more than 2 million absentee ballots requested statewide and mail returns running about 30 percent ahead of the same point in the 2022 midterms.

A toss-up seat with national stakes

The seat, held by retiring Sen. Gary Peters, is rated a toss-up by the Cook Political Report and is one of roughly ten contests both parties consider likely to decide whether Republicans keep their current 53-47 Senate majority. Democrats need a net gain of four seats nationally to retake control; Republicans need to defend most of their current ground.

El-Sayed, a physician and former Michigan health director, narrowly defeated Rep. Haley Stevens in the August Democratic primary after a bruising contest in which Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez backed El-Sayed while Senate Democratic Leader Chuck Schumer supported Stevens. Rogers, a former congressman and ex-chair of the House Intelligence Committee, is making his second consecutive run for the seat after losing to now-Sen. Elissa Slotkin in 2024 by roughly 19,000 votes out of more than 5.5 million cast — one of the narrowest Senate results in the country that year. Campaign finance filings with the Federal Election Commission show El-Sayed's committee, Abdul for U.S. Senate, and Rogers' committee, Team Rogers, have each raised millions of dollars this cycle, with both campaigns and allied groups pouring money into Michigan's airwaves through Election Day.

What the polling shows

A Marist Poll released Oct. 21, based on interviews with 1,185 Michigan registered voters conducted Oct. 15-18, found El-Sayed leading Rogers 50 percent to 48 percent among likely voters, a gap within the poll's 4.3-point margin of error, and leading by seven points among independents. In the governor's race, the same poll put Secretary of State Jocelyn Benson six points ahead of Republican Rep. John James among likely voters. Other recent surveys, including from Rasmussen and YouGov, have shown single-digit margins in the Senate race, with El-Sayed ahead in most but not all releases.

Benson and James held two televised debates this month, on Oct. 6 in Grand Rapids and Oct. 15 in Detroit, trading accusations over health care costs, tariffs and data-center development, while El-Sayed and Rogers met for their own first debate on Oct. 8. Detroit Mayor Mike Duggan, a Democrat, is also on the gubernatorial ballot as an independent in the race to succeed term-limited Gov. Gretchen Whitmer.

Who is showing up, and why

Obama's Detroit appearance, running from 5 to 7:30 p.m. and organized through the Michigan Democratic Party's coordinated campaign, One Team Michigan, is part of a broader midterm push in which the former president has taped roughly two dozen ads for Democratic Senate and governor candidates and campaigned for tickets in Iowa and Texas in recent weeks. He endorsed El-Sayed in an ad released Oct. 12. El-Sayed has also had to manage past comments criticizing Obama's record on war and deportations that resurfaced during the primary, which he has attributed to being "angry" at the time.

Trump's Sunday stop, at the McMorran Place Arena in Port Huron, is being staged by the Trump 47 Committee, a joint fundraising arrangement that combines his Save America committee with the Republican National Committee and other party organizations, with doors opening at 11:30 a.m. ahead of 3 p.m. remarks. Trump endorsed Rogers for the seat in mid-2025, and Rogers has pointed to that backing while also courting the Democratic and independent voters who gave Slotkin her narrow 2024 win.

"Michigan is a battleground state, and with Mike as our candidate, I know we will add this seat to President Trump's Senate Majority in 2026," Sen. Tim Scott, chair of the National Republican Senatorial Committee, said when Rogers entered the race.

Trump has also weighed in on Obama's involvement from the trail. At a rally outside Wichita, Kansas, on Oct. 19 for Sen. Roger Marshall, Trump dismissed Obama's effect on the race and referred to him as a "rotten president," part of a broader attack on Democratic efforts to campaign for El-Sayed.

Who is affected, and what comes next

Michigan voters will decide not only the Senate seat but an open governor's race, open contests for secretary of state and attorney general, and control of the state legislature — races both parties say will shape redistricting, abortion policy and election administration in the state for years. National Democratic and Republican committees have treated Michigan as one of a handful of true battlegrounds nationally, alongside Maine, North Carolina, Ohio, Iowa and Georgia Senate races, any combination of which could tip the chamber.

With early voting opening the same weekend as the rival rallies, both campaigns are explicitly framing the events as turnout operations rather than persuasion efforts this late in the race. Ballots cast during the Oct. 24-Nov. 1 early-voting window, plus absentee ballots already returned, will be tabulated alongside Election Day votes on Nov. 3, when Michigan — along with contests nationwide — will help determine whether Republicans keep unified control of Washington or Democrats retake at least one chamber of Congress.
