Graham Platner’s Maine Senate candidacy is a test for the socialists and progressives taking over the Democratic Party in what has been described as a Tea Party-like revolt from the Left.
Platner could jeopardize the Democrats’ chances to win control of the Senate if his multiple scandals prevent him from defeating Sen. Susan Collins (R-ME) in a much bluer state than the other GOP-held seats that are believed to be in play this year.
New York Times interviews with Platner’s ex-girlfriends that included accounts of physical abuse and emotional instability followed a Nazi tattoo that he has since covered up, controversial Reddit posts, and recent sexting during his marriage.
In years past, the Democratic establishment might have nudged Platner out of the race by drying up his campaign donations or urging him to drop out. But in 2026, left-wing insurgents such as Sen. Bernie Sanders (I-VT) and Rep. Alexandria Ocasio-Cortez (D-NY) can raise money, provide organizational strength, and hold sway over the nomination process that rivals that of Senate Minority Leader Chuck Schumer (D-NY). Rep. Ro Khanna (D-CA) rallied with Platner on Friday night.
Schumer’s preferred candidate for the Maine Senate seat, Gov. Janet Mills (D-ME), suspended her campaign when she fell well behind Platner in the polls. Schumer and Democratic leaders reconciled themselves to a Platner nomination in order to keep the race against Collins competitive.
As Platner-related controversies grew, Mills reminded voters that she remains on the ballot for Tuesday’s primary, but given the early vote, it would take a sizable shift in the Election Day vote for her to win.
Democrats are otherwise heavily favored to make gains in Congress in November, with a lead of 6.4 percentage points in the generic congressional ballot, according to the RealClearPolitics polling average.Â
Republicans hold a slim majority in the House that can be washed away by something less than a full-on blue wave.Â
But Republicans have a somewhat bigger majority in the Senate, and Democrats will need to do well in states much redder than Maine — Ohio, Iowa, Texas, Alaska, and North Carolina, among them — to flip the upper chamber.
The conservative Tea Party movement took advantage of a Republican wave election to take control of the House, ending a Democratic majority that was much larger than what House Speaker Mike Johnson (R-LA) has to work with right now.
Republicans gained 63 House seats in what then-President Barack Obama called a “shellacking.”
Nevertheless, Republicans failed to win back the Senate because some of the Tea Party candidates Republicans nominated weren’t ready for prime time.Â
In the end, it took until Obama’s second midterm election four years later for Republicans to win a Senate majority.Â
Christine O’Donnell in Delaware and Sharron Angle in Nevada are among the Tea Party candidates who lost what were seen as winnable Senate races for Republicans.
Republicans aren’t out of the woods yet when it comes to candidate quality concerns. Scandal-plagued Texas Attorney General Ken Paxton defeated Sen. John Cornyn (TX) in a Republican primary last month, making the Senate race with Democratic challenger James Talarico more expensive and potentially more competitive.Â
But the left wing of the Democratic Party has taken the lead in defending Platner as controversies mounted, while more centrist voices such as Sen. John Fetterman (D-PA) have urged caution. A small number of Democrats have called on Platner to drop out, but Squad-adjacent lawmakers are full speed ahead.Â
Previous socialist winners, such as New York City Mayor Zohran Mamdani, ran cautious and conventional campaigns.
Some polls have shown the Maine Senate race tightening since the latest revelations. Collins easily outperformed her poll numbers when she last won reelection six years ago.Â
A Platner loss would make the leftward movement inside the Democratic Party an electoral mixed bag at best.
