Everybody knows Biden will run and everyone knows he will get the nomination. Why is he waiting??
I think if he announces, then he becomes the Dem front-runner and therefore the target for all attacks. He already has the name recognition--he doesn't really need to start super early.
And he's already said Stacey Abrams will be his running mate. This is going to be AWESOME!
He has to have a minority on his ticket. Otherwise he is just another old white guy running for president for like the 9th time.
