That’s it, in one phrase. The Democratic Left will (in my humble opinion) posture, show off, and have infights among various identity groups. They will thereby demonstrate that they are no more sane than The Donald. And THAT is what Trump must be hoping. At this point he is losing the Adult-in-the-Room vote, but if Identicrats act out enough he will seem no more loony than they.
Folks whose identity is based on extending their middle finger to everyone else - are they likely to change just because they have been elected to office?
If Pelosi can keep this gang of cats herded, maybe I will be wrong. I would love to be wrong.
