Another Republican turns away from donald trump. It’s not clear what his response will be, as he has been generally absent from the public eye for weeks.
Who knows how long his campaign can last with Republican Senators speaking out against him? Maybe a heavily scrutinized press conference might be necessary, with his leadership skills (and mental capacity) in doubt.
Any vote for anyone other than Biden (or whoever replaces him if he steps aside) is a de-facto vote for Trump, no matter how you try to justify it to yourself. Susan Collins knows this. She is fooling nobody.
