Cruz has name recognition courtesy of the Dems and GOPe that despise him! He has not announced he is even running; but I certainly would not under estimate him nor count him out, especially this early in the game. My prediction is that the big hitters like Bush and Romney will be fighting amongst themselves; Huckabee and Crist will join in because of their egos and will fizzle out. Let Bush and Romney spend their millions forcing the Clintons to spend their money in counter attacks. Either Bush or Romney will be left standing and at that time either Cruz, Walker, Jindal or Paul will enter the race. You will see the Dems scurrying trying to reinvent Clinton or persuading Warren to run. At that point in time the GOPe would be wise to back one of the new GOP stars; if they don't the GOPe will lose AGAIN!
The only other way that I see the GOPe possibly victorious is if ithey name either Cruz, Walker, Jindal or Paul as their running mates. Like TEA or not, the GOPe needs them more than TEA needs the GOPe. I sure as hell will NOT vote for Bush and remain skeptical voting for someone who has already lost twice.
