The delegate math favors Trump in a couple of major states...
However.....
His own incompetence in the delegate process in places like Wyoming and Colorado are at the point that it will prevent him from getting to 1237.
If he doesn't make 1237, the field resets and the second ballot is strongly influenced on who created the better ground game in the States- in other words, who has an operation in place that can run better in the general election.
In some ways, it is like football. Even if you get to the 5 yard line on 4th down, if you don't score, you don't get to continue at the 5 yard line. You better hope you have a good defensive line. If you are all offense, that getting to the 5 yard line won't mean a hill of beans if the opponent runs over you on the second run.
