I think O'Rourke has the best chance of that lot of being elected - the best of a bad bunch. I think Warren would be battered personally.
Sanders is too much of an extreme opposite of Trump. The way to win for the Dems is to appeal to the moderates who may have voted Trump but regret doing so.
For all of Biden's faults (many of his policies) he crushes Trump. Just sets him ablaze. No one has ever been better at taking down phony bullies on the campaign trail than him.
