I assume you mean George Bush? It would stand to reason since Bush is from Texas. For instance, Jeb is Rubio’s mentor and they are both from Florida. One thing we know from Cruz’s record, he’s waaay more conservative than any Bush. Rubio only scores 80% (one point from a C ) on Conservative Review, with Cruz taking a solid A.
I believe I read, and I could be mistaken, that Cruz was part of the GWB FL recount.
