Susan Collins is up for reelection this year and is the one most likely at risk of losing her seat. There is no upside for her personally to vote on a nominee before the election, only downside. If she votes to confirm it energizes her opponent's voters to vote her out. If she holds off on a vote she can dangle the nomination over the Republican voters in Maine and say, "better keep me in or you won't get a conservative nominee confirmed."
Of course, she could just do the right thing based on principal, but looking at her track record we all know that won't happen. She loves pretending to be a centrist and having an inordinate amount of influence in these matters. Much more than a senator from Maine would/should ever have.
And right on cue, here comes Susan Collins trying to have her cake and eat it too.
Collins issued a statement Saturday afternoon in which she expressed her mixed sentiments about the succession of Ruth Bader Ginsburg.
She said in the statement:
In order for the American people to have faith in their elected officials, we must act fairly and consistently — no matter which political party is in power. President Trump has the constitutional authority to make a nomination to fill the Supreme Court vacancy, and I would have no objection to the Senate Judiciary Committee’s beginning the process of reviewing his nominee’s credentials.
Given the proximity of the presidential election, however, I do not believe that the Senate should vote on the nominee prior to the election. In fairness to the American people, who will either be re-electing the President or selecting a new one, the decision on a lifetime appointment to the Supreme Court should be made by the President who is elected on November 3rd.
