His problem is the infatuation with the amateurs, Trump, Carson, and Fiorina, who are garnering all the attention. Once they fold, one by one, Cruz will rise. We are still a long way away from any delegates being chosen.
Three people ahead of him have to fold? hahahahahaha.
Cruz' problem is that he is not connecting with the voters. He comes across as too preachy and zealous. He lacks the charisma and presence of a Trump or Fiorina and the likability of a Carson. The MSM has effectively painted him as "far right" and an extremist. I don't know how he gets out of that box.
If it ever came down to Cruz versus Rubio, Rubio would win and next to Bush, he is the last person I want to see as the nominee.
