Yes.
The bad news is that all of the pre-March 15 primaries, including Texas, are proportional representation.
The post-3/15, winner-take-all primaries, are in more liberal states.
I'm sure Priebus set this up to help Yeb!, but it will help Trump, who leads Republican voters in the moderate/liberal category.
I thought it was after 3/1. Geez, we can't seem to catch a break.
So Jeb thought he could grab up enough votes in the proportional states to justify staying in — then the more lib states would give him the coronation.
Priebus planned it so well, he thought. Plan B is to just knock out everyone else while trying to keep Jeb above the fray.
