I listen from time to time and notice that he props up Cruz when Cruz is down and props up Trump when Trump is down. And now he is openly backing Rubio, the establishment candidate.
He seems to be trying divide the anti establishment votes between Trump and Cruz so that Rubio can be the nominee. Not going to work. His influence is overrated.
He is not endorsing anyone if he says something nice about a candidate. He has said nice things about many of them. It is obvious he loves Trump's in your face against the establishment, as well as Cruz' consistency. He will never tell us who he is going to vote for in the primary.
I think you should stop listening. You obviously have no ability to understand simple talk. You are so invested and have so much angst about your candidate, that any perceived cough or sneeze in the wrong direction leads you to accuse. A simpleton, you are.
Besides, Rush has always said his influence is overrated. He has said if his influence is so great, why is Obama president.
He has always said to vote for the most conservative candidate that can win the general election. In fact, he has been so nice to Trump that many people thought he had endorsed him...but they are simpletons, too.
