@stephenjudkins right. private vindictiveness has been common, you are shunned with a smile while all your opportunities dry up. (i don’t love that either!) but Trump brought in a very public pile-on kind of vindictiveness, the thrill of “retribution” as part of the electoral appeal. and people like desantis took note.
@stephenjudkins (the necessity of pelosi style vindictiveness has been i think related to a discipline arms race within the two parties. i don’t think that’s been benign, though each party finds it necessary in the dynamic. the combination of only two parties plus strict discipline makes representation impossible. two leaderships is not enough to meaningfully represent the public.)
