Amid all the current rants on DU about spineless Dems, an ugly theory that first occurred to me during the Bush years is

cropping up again --
If one day there suddenly was a whistle blown in front of both houses of Congress, with the announcement "Everyone now switch places!", so that Dems had to become Republicans and Republicans became Democrats, many of them would have no trouble changing their sides and being able to now give convincing-sounding arguments for whatever their positions had changed to. Of course there were notable exceptions in both houses of Congress who did show by their actions how much they fervently and sincerely espoused Democratic ideals, but in general the more I looked at the news with this ugly theory in the back of my mind, the more it scared me. But I successfully pushed it out of my mind after Obama got in and then last year, with Trump getting convicted of 34 felonies, it wasn't something I thought about.
But after Trump managed to emerge from the felony with no consequences and win the U.S. presidency, those awful thoughts started cropping up again, starting with my finding out the details of Aileen Cannon's confirmation as federal judge.

The Senate vote of her confirmation makes no sense -

She won confirmation because she needed a majority of votes and got 56 Yeas. 12 Democrats voted Yea and 23 did not vote! If all Democrats had simply voted Nay for a clearly unqualified and inexperienced person nominated by Trump after he had already lost the 2020 election, she would not have been confirmed and possibly a more objective judge would have been confirmed.

Where do we go from here?
