Susan Collins will remain in the Senate, and that means another Republican voice that refuses to vote for an extreme agenda. The Washington Post:
Sen. Susan Collins of Maine announced Friday that she will not run for governor in 2018, renewing her commitment to serve in a sharply polarized Senate where her centrist Republican positions have made her a key bulwark against much of President Trump’s agenda.
Ending months of speculation about her political future, Collins, who does not face reelection until 2020, opted to stick with the job she has held for the last two decades, even as other moderate GOP lawmakers including Rep. Charlie Dent (Pa.) and Sen. Bob Corker (Tenn.) are heading for the exits.
“The best way that I can contribute to these priorities is to remain a member of the United States Senate,” Collins told the business crowd, capping a speech in which she described her role as a bipartisan figure on such issues as health care and national security in Washington.
[...] Collins read aloud a letter from a Senate colleague: “The institution would suffer in your absence. There are very few who have the ability to bring about positive change; you are such a person.” Her final decision, she said, came down to “my sense of where I can do the most for the people of Maine and for the nation.”
