As the Election Day approaches and Biden victory becomes more and more likely, voters who dislike Trump will start to fear a Democratic trifecta. I believe they will break for Collins so that she could be a check on Biden. After all, she has track record of being a moderate and independent thinking and not following the party line.
Lol, she voted for the Trump tax plan and Kavanough. She only votes against Republican leadership when she is allowed to because they already have the votes. Republicans have her vote unless she isn’t needed.
If Collins was so independent and such a “moderate hero”, she would be actively working right now to stop ACB’s confirmation.
