I am going to believe my own ears. I know what I heard when I listened to his show. If you want to rewrite history that is up to you. Rush had always stated he supported the Conservative candidate and stated many times that Trump was not a Conservative. Did you not hear that?
Never once did I hear him give his support to Rubio or any other candidate in the primary, which is the crux of your conversation.
With that being said, once Trump was the Republican nominee, Rush has been a total supporter of him.............Just as he has every Republican candidate in the past........So shove it!
As a post script, Rush analyzed and criticized every candidate in the GOP primary but never once did he show partisan support for Rubio, as you contend, or any other candidate. He provided the facts and let the voters decide............You seem to have missed that.
