Trump did say on O’Reilly this week that both Rubio and Cruz lack experience in the private sector and being job-creators. Just a couple weeks ago Trump wouldn’t say a bad thing about Carson. Look how that changed. Trump targets anyone who stands in his way to the nomination and he will savage Cruz if Cruz gets close. Then the conservative base will be split and at war with ourselves like we’ve never seen.
What Trump doesn't seem to realize is that the President does not create jobs, and we don't want the President to create jobs - we want the President to help get the government out of the way and let the private sector create the jobs. If Trump wants to be the job-creator-in-chief, he should stay in the private sector.
