Senator Susan Collins (R-ME) has been running election ads for months, but it wasn’t until Wednesday—on the eve of the Impeachment vote—that she officially announced that she intends to seek her fifth term.

Collins made it official in a letter to her supporters:

“The fundamental question I had to ask myself in making my decision was this: in today’s polarized political environment, is there still a role for a centrist who believes in getting things done through compromise, collegiality, and bipartisanship?

I have concluded that the answer to this question is ‘yes,’ and I will, therefore, seek the honor of continuing to serve as Maine’s United States Senator.”

While Collins may wish to continue “to serve”—and the Republicans desperately need her to maintain their majority—it is unclear whether the people of Maine still want her in that Senate seat.

In 2014, Collins took in 67% of the votes to win her fourth term in the Senate, but much of her support soured when she decided to confirm Supreme Court Justice Brett Kavanaugh. After that vote, her disapproval rating jumped to 50%.

Collins likes to cultivate an image of being a centrist, but her vote to put Kavanaugh on the Supreme Court and the 21 times she has voted against the Affordable Care Act point to her being further right than she likes to pretend.

In fact, her votes have aligned with the Trump agenda roughly 94% of the time.

With the impending impeachment trial in the Senate, Collins will have to vote on the acquittal or guilt of President Trump. In addition, she will be part of the decision on whether there should be any witnesses. Many of the potential witnesses are quite popular with a large number of Republicans and an even larger number of independents.

The Senator may have a fierce battle ahead of her if she hopes to win re-election.

There are currently four Democrat contenders for her seat including Sara Gideon, the Maine House Speaker, who has the backing of the Democratic Senatorial Campaign Committee.
