The Sanders supporters will be raising hell.
They should be raising hell. It’s pretty obvious what probably happened tonight. Biden likely got creamed. He came in a distant 3rd, 4th or worse, so word came down from the DNC to the powers that be in Iowa to turn the evening into a dumpster fire to spare Old Joe from humiliation. It’s like the kid who didn’t do his book report pulling the fire alarm in hopes of mucking up the school day and put himself in the position of mitigating personal disaster.
