Only three delegates said they plan to vote for Cruz on the first ballot. Nine others are uncommitted.
I think you've missed the events of the last 2 months where Trump supporters are threatening the lives of delegates and their families if they publicly announce for anybody but Trump.
But you go on with your belief that NOT publicly stating they won't vote for Trump means they WILL vote for Trump.
The panic and counting of delegates every 5 minutes is kind of funny. Sit back and relax. All Trump has to do is walk in with 1,237 delegates to vote for him. Most likely will happen as long as he acts like a decent human being for 3 months.
