Go with Jeb and he won't win the GOP vote in the General
You are repeating yourself. In New Hampshire (of all places) he actually had the highest favorability rating. (Trump, of course, has the highest vote total, but a lot of people who like Trump also like Cruz)
Have you seen Cruz in person? I have, three times. He came across better than Rubio, and on par with Christie, who actually gives a very good presentation and knows how to tailor his talk to his audience.
Cruz doesn’t have to be as likable as Jimmy Stewart or Cary Grant, just more likeable than Hillary Clinton.
The guy is a frothing Trumpty Dumpty.
