The only candidate who will get any sort of African-American support is Joe Biden. I think the Sanders supporters will get ewscrayed again. That African-American support will be vital down ticket for the Dems. You nominate Buttigeg, Princess Grey Beaver, or Komrade Sanders, blacks will stay at home even more than tney will with Biden.
Any nominee besides Biden for the Dems will result in a veto-proof House and filibuster-proof Senate for President Donald Trump and the Republicans.
Of course they know he’s gonna win . that’s why the last hail Mary the deep state has 2 options: this impeachment garbage or the jfk way..
