Democrats’ civil war heads to Michigan where progressives face biggest test yet in high-stakes Senate showdown

The high-stakes fight between the left-wing and the center-left establishment for the future of the Democratic Party is moving to a much larger stage.

After victories by far-left and socialist candidates in dark blue congressional districts in New York City and Colorado the past two weeks drew national attention, the spotlight now shifts to battleground Michigan.

That’s where moderate Rep. Haley Stevens, D-Mich., who is backed by Senate Minority Leader Sen. Chuck Schumer, D-N.Y., and the establishment; and former Wayne County Health Department Director Abdul El-Sayed, a left-wing candidate endorsed by progressive champions Sen. Bernie Sanders, I-Vt.,and Rep. Alexandria Ocasio-Cortez, D-N.Y., are colliding in a crucial Senate showdown.

The winner of the Aug. 4, 2026, Democratic primary will face-off in the midterm elections in November against former Republican Rep. Mike Rogers, who is on a glide path to the GOP nomination. The winner will succeed retiring Michigan Sen. Gary Peters, a Democrat. 

CRUCIAL SENATE BATTLE ROCKED AFTER MAJOR PLAYER DROPS OUT OF RACE

The seat is a top Republican target and is a must-hold for the Democrats as they aim to win back the Senate majority from the GOP, which currently controls the chamber with a slim, but manageable, 53-47 margin. The leading nonpartisan political handicappers at Cook Political Reporter rate the Senate race in Michigan as a toss-up.

Matt Bennett, one of the leaders at the Third Way, a leading center-left Democratic organization, told Fox News the primary in Michigan “is much more significant” than the intra-party ballot box showdowns the past two weeks in “very, very blue districts” in New York City and Denver.

The showdown in Michigan became a two-way race on Sunday, after progressive state Sen. Mallory McMorrow, once the third major Democrat in the primary, suspended her campaign.

“I may be suspending this campaign, but I am not leaving the fight,” McMorrow pledged in a statement Sunday as she ended her Senate bid.

McMorrow, who has seen her national profile expand in recent years and was running as a progressive in an ideological space between El-Sayed and Stevens, suspended her campaign amid faltering poll numbers and fundraising that weren’t keeping pace with her two main rivals.

McMorrow pledged to fully support whichever Democrat wins the primary and will ultimately face-off with Rogers, who is running for the Senate for a second straight cycle after losing in 2024 to now-Sen. Elissa Slotkin by a razor-thin margin.

Following McMorrow’s announcement, Stevens praised her fellow Democrat by calling her an “important voice” for policies that benefit Michigan families. Stevens then argued that she is the strongest Democratic candidate to win the primary and defeat Rogers in November.

“As we enter the final month of the primary election, I’m excited to continue to make my case to Michiganders why I’m the strongest Democrat to defeat Mike Rogers this November, lower costs, protect manufacturing jobs, and stand up to Trump’s abuses of power,” she added.

As she runs for the nomination, Stevens has been backed by millions in super PAC spending, including big bucks from Israel-aligned groups.

In his statement, El-Sayed praised McMorrow for having the “courage” to challenge what he described as a rigged political system, accusing Democratic Party insiders of spending millions to influence the primary. While he did not name specific groups, the remarks appeared to reference corporate PACs and establishment party leaders such as Schumer.

He then invited McMorrow’s supporters to join his progressive movement to combat big money in politics and defeat the political establishment.

“Throughout this campaign, Senator McMorrow showed what it looks like to fight back against politics that rigs the system against too many of us. While we have policy disagreements, I never questioned whether Senator McMorrow would fight for a better America for my daughters and hers,” he said.

“The same party insiders she had the courage to challenge have been bullying anyone who opposes their chosen candidate. After spending $30 million to drown Senator McMorrow and me out, they’re now spending even more to attack me. It’s everything we are standing up against.”

“I welcome her supporters to our movement to stand up against money in politics, to put money back in pockets, and pass Medicare for All. We cannot allow the establishment to decide our nominee for us.”

THESE MIDTERM RACES WILL DETERMINE WHETHER REPUBLICANS HOLD THEIR SENATE MAJORITY

El-Sayed, who, if elected, would make history as the nation’s first Muslim senator, is an epidemiologist who unsuccessfully ran for governor as an insurgent candidate in 2018. He has made support for “Medicare-for-all” a major component of his campaign.

The far-left candidate has also called for abolishing Immigration and Customs Enforcement (ICE), and is a vocal critic of Israel amid its war with Hamas — even characterizing Israel’s actions in Gaza as “genocide” against Palestinians.

And El-Sayed, who served as a top surrogate on Sanders’ 2020 presidential campaign, has vowed not to accept PAC donations.

Schumer and the party establishment view Stevens as more electable than El-Sayed, who has sparked controversy with his past comments. They worry that El-Sayed as the party’s nominee would jeopardize the Democrat-controlled Senate seat by pushing the party too far to the left in a state that President Donald Trump carried two years ago by just over one percentage point.

A victory by El-Sayed over Stevens in next month’s primary would give the far left a major win on a statewide stage, and further boost their momentum in the battle for the Democratic Party’s future.

But Bennet warned against placing too much emphasis on the results in Michigan, as he pointed to other factors in the race.

“I don’t think that even if El-Sayed wins, that means the national party is moving dramatically to the left, as the left will insist if that happens,” he told Fox News Digital. “Some of this is idiosyncratic. There’s a huge Arab American population in Michigan. The Israel issue is more resonant there than it is in other places. And candidates matter.”
