Which March 1st states do you expect a candidate to hit 50% in? I have a hard time seeing that happening right now.
Here are the ones that have that rule:
Alabama, Arkansas, Georgia, Oklahoma, Texas, and Vermont
It’s an outside chance, but Cruz could do it in is Texas.
I can see Trump pulling over 50% in some of the others...depending on what happens between now and then.
You may see Christi, Fiorinia, Kasich and carson all drop out between now and then.
