For Bloomberg or Sanders to win, the USA would have to elect it's first jewish President. (Not gonna happen)
Buttwedge would be the first openly gay President. (Not gonna happen)
Liz Warren would be the first fake Indian President. (Not gonna happen)
The calibre of these people shows how dejected the D's are. They know they can't win so they're using 2020 as a litmus test to see just how much fuckery American leftists will tolerate. Turns out it's quite a lot.
