Buttgig is Hillary’s new stalking horse.
This race is really just Hillary vs. Sanders again. The former is simply trying to sneak in the back door by creating a brokered convention. Thus all the Hillary-ally vote splitters making sure no one gets momentum.
But as each one sucks and the bottom falls out - Harris, Biden, Warren, either someone else gets in to keep splitting the vote, or they pick someone else to artificially elevate and hope it sticks long enough to split delegates.
Well it’s obvious Warren’s roll is take Bernie votes now. Now that Poofter Pete is close if she keeps getting he 10-15% Bernie will fall just short of winning which is exactly what the DNC wants. They rigged Iowa just right. Take just enough Bernie votes to keep him from winning but not so many that it is an obvious screw job. If Bernie’s base believes he got screwed they stay home which will kill any chance the rats have.
