Pass the Popcorn; The Donald Ed.

Donald Trump stepped up his fierce attacks on his own party leaders Tuesday, promising to teach Republicans who oppose him a lesson and fight for the presidency "the way I want to."

Meanwhile, bet that the professional GOP party workers, the ones who run get-out-the-vote campaigns, are going to quietly drop their tools and walk away.

Talk about a high-stakes gamble, with nobody to buy into his operation and bail him out.
