Democrats will not nominate a white guy, and both Biden and Bernie are over 70.
But really, who else do they have?
The only black guy running is Cory Booker. You have Julian Castro, a Hispanic man, but his star faded long ago.
The two leading women, Elizabeth Warren and Kamala Harris, fester with so much hatred that most sane people could not bring themselves to vote for either one of them... even Democrats. The general election polling shows that, with both consistently polling the worst in a head-to-head with Trump compared to other candidates.
The rest? Young white guys whose stars rise and fall with the tide.
The Democrats will talk and talk and talk about not wanting to nominate a white guy again, but really, what choice do they have?
