They all have their strengths and weaknesses. Bernie is flush with cash, but he’s a communist who supports felons voting from the execution chamber. Biden doesn’t excite any of their wacko intersectional groups, but he’s less likely to support say dropping atom bombs on people who won’t turn in their guns.
Bernie went up against the massive Clinton machine and almost won.
Biden is a befuddled old fool that ran twice before disastrously.
Sanders has the fire of a Bolshevik, and the morals to match.
His team will cut through Biden like a buzzsaw. They want payback for the 2016 primaries, and they arent taking 2nd.
