When Gov. Janet Mills announced the end of her fading U.S. Senate campaign on Thursday morning, responses from around the state came pouring in.

With the governor bowing out, it’s looking all but certain that Graham Platner will secure the Democratic nomination and face incumbent Sen. Susan Collins in November. Other than Platner, the only Democrat remaining in the primary is David Costello, a Brunswick resident who is well behind in both polling and fundraising.

Many of the Democratic reactions Thursday congratulated Platner and declared him the presumptive nominee. The Democratic Party and associated groups — as well as many state and local politicians and office-seekers — lined up behind the oyster farmer and military veteran from Sullivan. But notably, Mills did not immediately endorse her former primary opponent.

On the other side of the aisle, Republicans took aim at both Mills and Platner, casting the former as an out-of-touch career politician rejected by voters and the latter as an extremist who they argued is unfit to represent Mainers.

Our live updates for the day have ended. Scroll through below for a recap of Thursday’s events.

Janet Mills not eager to endorse Graham Platner

A campaign spokesperson for Gov. Janet Mills released this statement Thursday in response to questions about whether she would endorse Graham Platner for U.S. Senate:

“Governor Mills has never voted for Susan Collins, and she will not do so in this election either. As Maine’s Governor, she will continue to support Democratic candidates across Maine, and she will continue to hear and watch how Graham Platner works to earn the support of Maine voters, just as she will keep a close eye on Maine’s Congressional and Gubernatorial primaries as well.”

Maine Democratic Party ‘has lost its mind’, Republican U.S. senator says

U.S. Sen. Tom Cotton, R-Arkansas, criticized the Democratic Party on Thursday as the way was cleared for Graham Platner to become the party’s nominee for U.S. Senate.

“Democrats are rallying behind a self-described Communist with a nazi tattoo in Maine. The party has lost its mind,” Cotton wrote on X. “Susan Collins has spent her career standing up and delivering for Maine families. She’s ready to win this fight.”

National Republican Senatorial Committee blasts Platner

Predictably, the campaign arm of the U.S. Senate Republicans criticized Graham Platner, who’s almost certain to be the Democratic nominee for U.S. Senate.

“Chuck Schumer and Senate Democrats just coronated a phony who is too extreme for Maine. Susan Collins has always put in the work for her constituents and delivered. Washington Democrats always fall short in Maine and will again, because they just nominated a dishonest radical,” said NRSC Chairman Tim Scott in a statement.
