Former President Trump won Maine’s GOP primary Tuesday, according to a projection from Decision Desk HQ, boosting his Super Tuesday dominance.

Trump appeared on the ballot in Maine after an effort from Maine Secretary of State Shenna Bellows (D) to prevent him from participating in the primary. Trump appealed the decision to a state court, which ruled Trump could stay on the ballot until the Supreme Court resolves a similar case from Colorado.

Bellows appealed the ruling and, in late January, the Maine Supreme Judicial Court upheld a lower judge’s order that required Bellows to wait for the Supreme Court’s Colorado decision.

Trump’s win in Maine was another hit to GOP candidate Nikki Haley. He has dominated the Republican primaries, including in Michigan last week and in South Carolina earlier this month.

Maine held its first-ever semiopen primary this cycle, which allows unenrolled voters to participate and choose between a Republican or Democratic ballot when they arrive at the polls.

Biden beat Trump in Maine in 2020 with more than 53 percent of the vote.
