If Trump has the most delegates going into the convention (but not 1237), the GOP has two choices:
1. Go with Trump (who could beat Hillary), and try to win as many downline contests as possible: Senate, the House, State Houses and Governorships.
2. Screw Trump GOP voters at the convention, and lose EVERYTHING.
The GOP would help Trump get the nomination if he were the best candidate to beat Hillary. He isn’t. Trump is a turnoff to many conservatives and moderate Republicans. He would lose the general election against Hillary or Biden.
