Republicans Pour $45 Million Into Michigan Senate Race as GOP Sees Key Pickup Opportunity

A national Republican super PAC announced Monday it is investing $45 million into Michigan's open U.S. Senate race, marking the organization's largest and earliest ever commitment to any state in the midterm election cycle.

The Senate Leadership Fund (SLF), a super PAC affiliated with Senate Majority Leader John Thune of South Dakota, said the spending makes Michigan the GOP's top priority for flipping a seat from Democratic control this November.

"These ad reservations will begin in late August and cover Michigan's entire early-voting period," SLF Executive Director Alex Latcham said in a statement released Monday. "The large and early investment by SLF this cycle is a nod of confidence in Rogers' team after he largely cleared the primary field and locked up President Donald Trump's endorsement last summer."

The $45 million commitment represents more than double what the group spent in Michigan in 2024, when it didn't jump in until September 30 — less than a month before the election. Last cycle, the Senate Leadership Fund spent $34.33 million on Michigan operations. In 2020, when GOP nominee John James lost to Sen. Gary Peters, the group spent $17.75 million in Michigan.

This year's early investment ensures better television rates and more inventory availability than was possible last cycle, when the group waited until the final month before the election. The ad bookings will cover broadcast, cable, streaming TV and radio airtime, as well as data operations, direct mail, text messaging, field outreach, a ballot "chase" for unreturned absentee ballots and get-out-the-vote efforts.

The Michigan spending is the largest among the GOP's top pickup opportunities by state, with the group also announcing $44 million for Georgia and $17 million for New Hampshire. SLF is also spending millions to defend Republican-held Senate seats in Ohio ($79 million), North Carolina ($71 million), Maine ($42 million), Iowa ($29 million) and Alaska ($15 million).

Senate Majority PAC, the Democratic super PAC affiliated with Senate Minority Leader Chuck Schumer, responded by saying Republicans are pouring money into Michigan because they see it as a vulnerable seat.

"Without Trump on the ballot, Rogers needs every dollar he can get," Senate Majority PAC Press Secretary Christyna Thompson said. "The GOP knows they've got a weak candidate who's already burned millions of their dollars last cycle. But none of that changes the math: Rogers is shackled to an out-of-touch agenda that's deeply unpopular with the voters they're trying to win."

Rogers' Campaign Reacts

Mike Rogers, the presumptive Republican nominee who has President Trump's endorsement, marked one of only two endorsements announced by the Sentinel Action Fund this cycle. The conservative super PAC, partly funded by the DeVos family and including contributions from Elon Musk and hedge fund manager Paul Singer, announced it will spend $15 million with its affiliated organization Right Vote to boost Rogers.

"Michigan is a key pickup opportunity for Republicans in 2026, and Mike Rogers is the America First candidate who will bring conservative leadership to this important seat," Sentinel Action Fund President Jessica Anderson said. "He is dedicated to helping President Trump implement the policies that will defend manufacturing jobs in Michigan, put money back in Americans' pockets and solve the problems created by Biden-era inflation."

Rogers' campaign has been navigating his bid as though he has already won the August 4 primary. At the end of 2025, he reported having $3.5 million in cash on hand according to Fair Election Commission filings — the largest warchest of any candidate in the race.

However, Rogers' overall fundraising pace has lagged behind top Democratic contenders, who have posted stronger quarterly hauls and benefited from robust small-dollar networks. As of year-end 2025, Rep. Haley Stevens (D-MI) and Democratic state Sen. Mallory McMorrow each had over $5.5 million in individual contributions, while Rogers ended the year with $3.4 million in such contributions.

The Democratic Field

The eventual Democratic nominee is expected to face Rogers in what is shaping up to be one of the most expensive Senate races in the nation. Prominent contenders in the Democratic primary to replace retiring Sen. Gary Peters include U.S. Rep. Haley Stevens of Birmingham, state Sen. Mallory McMorrow of Royal Oak and former public health official Abdul El-Sayed of Ann Arbor.

On the fundraising front, McMorrow has emerged as a strong performer. State Sen. Mallory McMorrow raised over $3 million from 120,000 individual donors in the first quarter of 2026, according to her campaign. McMorrow has emphasized her rejection of corporate PAC money, though federal data shows she has received more than $34,000 from corporate PACs for her U.S. Senate campaign.

Stevens led fundraising among Democratic hopefuls last year, but McMorrow's recent quarterly haul has placed her ahead in early fundraising metrics. Campaign finance reports are due April 15.

What's at Stake

Republicans consider Michigan one of the best pickup opportunities of the fall midterm elections. The last time a Republican won a Senate seat in Michigan was in 1994, when former state Republican Party Chairman Spencer Abraham defeated former Democratic U.S. Rep. Bob Carr.

Analysts note that the last time the GOP won a Senate race in Michigan — in 1994 — was also the last year the state held a protracted, competitive Democratic Senate primary. This year's Democratic field, with multiple strong contenders, presents Republicans with a potential advantage.

Kyle Kondik, a political analyst at the University of Virginia Center for Politics, noted that Michigan remains the most plausible Senate Republican pickup opportunity in part because of uncertainty in the Democratic primary.

"What effect the spending has is up for debate — it may matter on the margins, but other factors, such as the quality of the two candidates and the broader political environment, will matter more," Kondik said.

The race comes as national Republicans unveil a broader $342 million battle plan to preserve Senate control. Michigan spending represents the largest share of that investment among pickup opportunities, reflecting Republican confidence in their ability to flip the state.

Last Cycle Comparison

In 2024, the last time a Republican contested the Michigan Senate seat, outside groups poured in $143 million. Slotkin spent about $50 million to help Rogers, who received $13 million in support from Republicans.

The SLF's commitment of $45 million this cycle will cover a comprehensive array of campaign operations, from advertising to voter outreach to early-vote operations. The timing — with ad bookings beginning in late August — gives the campaign a significant operational advantage over last year.

The Michigan Senate race remains one of the most closely watched contests in the 2026 midterm elections, with national parties and outside groups investing heavily in both candidates as they battle for control of the U.S. Senate.
