You need to go back on the Rush threads and see just how happy /s folks are with him.
Back during the primary a lot of freepers got their panties in a wad because Rush didn't go whole hog for their candidate. Some were for Bush. Some were for Trump. Some were for Cruz, Rubio, Kasich, etc. And there was great passion as people supported their chosen candidate. What did Rush do? He discussed and analyzed the news and gave his take on things. And those who were for Cruz were mad that Rush did not come out and openly endorse their candidate. So Rush must be a RINO and they weren't going to listen to him anymore. And those who were for Trump were mad that Rush did not openly endorse Trump. And so it went. If he did not openly promote their candidate, then he was the enemy.
After the primary was over, Rush gave his support to the winner, as he has always done. That doesn't stop him from analyzing the news or critiquing the candidate when he says or does something that does not help his campaign. Rush continues to give his take on events. As I said before, if Rush, the Master Communicator, has become a never Trumper as you claim, he is doing a remarkably bad job of trashing Trump and siding with those who would much rather have Hillary running the country than Trump.
