I respectively disagree. If Trump wins Iowa...it’s over. If Cruz wins Iowa or comes in second it means nothing, because he is stuck (in most polls) in single digits nationally.
-— he is stuck (in most polls) in single digits nationally -—
For two reasons. #1 is that conservatives who like him think he can’t win in the general election. #2 is that a lot of Republicans STILL don’t know him outside of the media caricature.
If he finishes #1 or #2 he becomes a potential *winner* and people will begin to listen to him.
Here is the ABC interview of Trump.
