“Then he and Cruz, along with Rubio combine delegates and screw the voters.”
Maybe.
by my count there’s 1313 delegates left. For Trump to win he needs to win 59% of them. He’s been winning ~39% so far.
If he only wins FL he then need 55% of the rest of the delegates.
Your numbers look correct. I think it will depend on a couple of winner-take-all states like California to get Trump the number he needs or deny him the majority in the first vote. If those contests were held today he would win them easily and I don’t see anything that would change that.
