In Maine, Senate Minority Leader Chuck Schumer<\/a> has thrown his weight behind Gov. Janet Mills<\/a> in a crucial race, but some of his Senate colleagues are backing insurgent candidate Graham Platner<\/a> in a rebuke of his strategic vision. A similar dynamic is playing out in other battlegrounds, including Michigan and Minnesota, where progressives senators are endorsing non-establishment candidates.<\/p>\n At stake is more than any single race. Democrats are fighting over whether the party\u2019s traditional playbook still works in a country that elected Donald Trump for a second time \u2014 and whether leaders like Schumer should remain in charge.<\/p>\n \u201cClearly there\u2019s a disagreement of strategy here,\u201d said New Mexico Sen. Martin Heinrich, who has endorsed Platner.<\/p>\n He added that \u201cthe business-as-usual calculation for what is going to be successful in a given election cycle does not necessarily, in my view, meet the moment.\u201d<\/p>\n The divide reflects a Democratic base frustrated<\/a> after the last presidential election, when President Joe Biden ran for a second term despite widespread concerns about his age. He dropped out and endorsed Vice President Kamala Harris, who lost to Trump.<\/p>\n Nan Whaley, a Democratic strategist in Ohio who ran for governor four years ago, said the debate is no longer about progressive or moderate.<\/p>\n \u201cIt\u2019s really about, who do you trust? Establishment or not establishment,\u201d she said. \u201cAnd frankly, the establishment hasn\u2019t given us a lot to trust these past few years.\u201d<\/p>\n \u2018A rebuke of Schumer\u2019<\/p>\n In Maine, Schumer and the Democratic Senatorial Campaign Committee, or DSCC, have backed Mills, a 78-year-old moderate in her second term.<\/p>\n Platner, a veteran and oyster farmer, quickly won the backing of Sen. Bernie Sanders, I-Vt., just days after launching his campaign. His bid has since gained momentum despite scrutiny over past controversial comments<\/a> and a tattoo resembling<\/a> a Nazi symbol.<\/p>\n In recent weeks, Heinrich, Arizona Sen. Ruben Gallego and Massachusetts Sen. Elizabeth Warren have endorsed Platner as he builds support on Capitol Hill. Heinrich and Rhode Island Sen. Sheldon Whitehouse held a fundraiser for him, too.<\/p>\n Gallego<\/a>, a first-term senator who won a battleground race in 2024, downplayed the endorsements as a broader critique of party leadership.<\/p>\n \u201cSenate leadership didn\u2019t back me at the beginning. So I didn\u2019t take that as a critique,\u201d Gallego said.<\/p>\n Michigan also has a contentious primary, with three high-profile candidates. State Sen. Mallory McMorrow has said she would not support Schumer as the caucus leader if Democrats regain the majority, and she\u2019s been endorsed by four senators.<\/p>\n Abdul El-Sayed, running further to the left, has been endorsed by Sanders and has also run on an anti-establishment platform.<\/p>\n U.S. Rep. Haley Stevens has aligned with establishment figures, working with a former DSCC executive director and securing support from two senators.<\/p>\n Democratic strategist Lis Smith said the endorsements in races like Maine and Michigan are \u201cas much as a rebuke of Schumer as it is an endorsement of these candidates.\u201d<\/p>\n \u201cIt\u2019s pretty uncommon for sitting senators to endorse against the Senate leader,\u201d Smith said. \u201cSenators are reading the tea leaves and are getting feedback from the grassroots that they are dissatisfied with Schumer\u2019s performance as leader.\u201d<\/p>\n In Minnesota, an open-seat race has similarly emerged as a test of the party\u2019s direction. Rep. Angie Craig is seen as the centrist candidate in the primary, with endorsements from House Democratic Leader Hakeem Jeffries and Rep. Nancy Pelosi. Lt. Gov. Peggy Flanagan, the more progressive candidate, has been backed by Sanders, Warren and others, including Minnesota Sen. Tina Smith, who is vacating the seat.<\/p>\n \u201cShe understands that right now what we need are fierce fighters, people who are willing to stand up to the status quo,\u201d Smith said in her endorsement.<\/p>\n Some tensions trace to March 2025, when Schumer voted<\/a> with Republicans to end a government shutdown, drawing backlash from Democrats who argued he did not push hard enough against Trump\u2019s agenda.<\/p>\n![](\"https:\/\/www.newsbeep.com\/us-ca\/wp-content\/uploads\/2026\/03\/Election_2026-Senate-Maine_56518_02bd83.jpg\"\/)
