He may be an honest communist, but as a pol, he’s corrupt to the core, funneling massive amounts of dough to himself and family. As for obama, he had his chance to make himself a billionaire in office, and it seems a little ungracious to interfere with sanders’s hopes for the same.

Bernie is doing fine, he now has three.
Most of the Democrats would rather not be honest about believing in communism.
Bernie at least makes no bones about it.
