“You all did it for me!” Biden yelled at 300 of his supporters at his caucus-night party at the International Brotherhood of Electrical Workers union hall in Las Vegas.

“Now we’re going to go on to South Carolina,” he threatened.

“We’ve got a chance!” he complained.

He berated the crowd with such insults as “Without you I wouldn’t be here today!”

In a final gesture of contempt, he then invited them to vote for the other Biden.
