Several southern states are trying to get the RNC to move their primaries earlier. Currently, those primaries are late in the spring. Thus, the nominee is usually selected before those primaries are even held.
If those states succeed and get their primaries moved to early March, that could put a wrinkle in the GOP elite push to coronate their establishment selectee.
I disagree- Texas has always (in my memory) been March 4, and that is way too late, by then it has already been decided, with conservatives having been already eliminated.
