Is that true? Who knows? If it is, it’s only because Biden either knew Obama would not endorse him or because, given where the Democrats are these days, an Obama endorsement would have HURT him.
Note Biden looks kind of elderly and can’t even answer the question of why he is the best Democrat in the field.
Bad start. This will not be the nominee.
The problem is, if not Biden, Bernie? Even Republicans should not want Sanders to be the nominee. A socialist should not be anywhere near the White House. Shouldn’t even be allowed to walk up Pennsylvania Avenue from Capitol Hill.
