Washington
Biden 47
Sanders 44
Warren 5
I guess all of Warren supports could back Bernie instead and half of undecideds break for Bernie. But I doubt it.
Crazy thing is, it seems the more Biden gaffes and displays what appears to be early to mid dementia, the higher he goes in the polls. Maybe he should get out there and say some really stupid crap that makes no sense. Oh wait.. He already did that!
