PORTLAND, Maine — Maine’s Democratic secretary of state on Thursday removed former President Donald Trump from the state’s presidential primary ballot under the Constitution’s insurrection clause, becoming the first election official to take action unilaterally in a decision that has potential Electoral College consequences. While Maine has just four electoral votes, it’s one of two states to split them. Trump won one of Maine’s electors in 2020, so having him off the ballot there should he emerge as the Republican general election candidate could have outsized implications in a race that is expected to be narrowly decided.
