We know that Susan Collins talks out of two sides of her mouth. She says one thing to make it look like she is serving the interests of Mainers, but does another, even though she might be "concerned." She has said that October is too late to vote on a Supreme Court nominee because it is so close to the election.
But what will she actually do? Will she pledge to not vote for any nominee Trump puts forward because it's too close? Or will she do her usual of going along with whatever Trump wants?
