Dont EVER forget......First and foremost....Rush is an “entatainer” FIRST!
Rush's number one priority is keeping a large audience. He lost me a long time ago. He loves the Bush family, which might explain his anti-Trump talk.
On a more positive note, I heard a woman today explaining why polls of likely voters, usually the most reliable, are missing lots of Trump voters. Many Trump supporters have never voted before and thus are not in the category of "likely" voters.
Rush uses the entertainer position when something he does isn’t right. His other default option is using the absurd to illustrate the absurd. When he says either of those, you know he blew it about something.
