Cruz and Trump seem to be the only non-GOPe candidates running—and Cruz himself is partial-GOPe, when you consider TPA/TPP, etc. (Don’t fool yourself into thinking they’re not behind Carson and Fiorina as well.)
Well, I almost agree... I would not include Carson in that group but he is not exactly what I would call a Conservative with some of his ideas. Fiorina is almost an insider, I agree and would probably rule as such. Cruz has been fighting the establishment since being elected so don’t think of him as even a partial part of the establishment although I can understand why you would say that as he has been in power for a while (but using his position to fight the establishment).
So, yes, I would love for Cruz (the ultimate Tea Party fellow) to shake things up and I think he would but of course so would Trump. Not sure anyone else running would.
Other than that, it just may not matter as it might be only another 4 years or so before things collapse beyond recovery. If they don’t get control of the debt then it just may not matter much at all...
