Sara Gideon (D), who lost her challenge to Sen. Susan Collins (R-ME) last November, still had $11.5 million in her campaign account on March 31, according to FEC filings.

“If Republicans are able to hold onto their majority in the U.S. Senate, the remarkable staying power of Susan Collins will be a big reason why,” the AP reports.

“Collins defied prognostications of doom from Washington’s consultant class to score perhaps the most unexpected victory of the 2020 cycle, hanging a lopsided loss on a Democratic challenger despite a pile of outside Democratic money and open hostility from the leader of her party, President Trump.”

“Revitalized and empowered, Collins now has the chance to wield her influence over a Senate where the sweet spot for President-elect Joe Biden’s agenda will be found somewhere in the moderate middle — the political space she’s happily called home for decades.”

Politico: Susan Collins reaches peak influence after Senate stunner.

Sen. Susan Collins said her Democratic opponent, Sara Gideon, called her to concede in the Maine Senate race, Politico reports.

Sen. Susan Collins (R-ME), who is locked in a close reelection race with Sara Gideon (D), warned to Hugh Hewitt that it could take a week to determine who won Maine’s U.S. Senate race.

Said Collins: “If neither of us gets 50 percent of the vote, then we get into the rather odd ranked choice voting… We probably would not know for certain who won for another week.”

Sen. Susan Collins (R-ME) told the New York Times that she briefly considered running for reelection as an independent but ultimately decided to stick with her party because of loyalty to “the New England brand of Republicanism.”

President Trump slammed Sen. Susan Collins (R-ME) this morning:

“There is a nasty rumor out there that Senator Collins of Maine will not be supporting our great United States Supreme Court Nominee. Well, she didn’t support Healthcare or my opening up 5000 square miles of Ocean to Maine, so why should this be any different. Not worth the work!”

Of course, the “nasty rumor” is actually Collins’ statement from last month saying she would not vote to confirm a nominee before the election.

Sen. Susan Collins (R-ME) went after Sara Gideon (D) in a Politico interview and accused the State House speaker of “defaming my reputation and attacking my integrity.”

Said Collins: “She will say or do anything to try to win. This race is built on a foundation of falsehoods. And trying to convince the people of Maine that somehow I am no longer the same person.”

Also important: “Gideon’s narrow polling lead could be even stronger when Maine’s ranked-choice voting system is taken into account… Among the very small sample of respondents not planning to pick one of the major-party contenders as their top choice, Gideon is much more popular than Collins as a second-choice vote.”
