Not unlike the Russian pawn Jill Stein, Sinema had roots in the Green Party -- often bankrolled by GOP megadonors in order to spoil the vote. Psychopaths with no loyalty go to the Green or Libertarian parties to get some easy money and set themselves up for a future in heartless lobbying to spoil on behalf of the other side.

The best you can do is hope for is a long history of public service and taking hard stances before they were popular -- in other words, leading from the front with courage (like Sanders for example).

With Fetterman one cannot fully rule-out the massive stroke he had, which commonly alters behavior as he had an extensive public service history and at least in my view at the time was more progressive pre-stroke.

I am very curious to see who rises to the occasion in PA to take his seat in '28
