Trump will gain delegates in districts that are huge majority Democrat.
For example he gets three delegates for a district that votes 90% Democrat and based on a handful of votes he gets three delegates, the same as if he won a district that is heavily republican.
This is how he is benefitted by the establishment rules.
Idiot Cruz just won delegates in a whole state that hasn’t voted republican since 1984. No difference. Nice try at your dribble again. Loser Cruz another third place finishes. He should be getting used to third place by now.
