He came under A LOT of heat from Democrats for not instead ranting at Republicans and it appears he saw the light, regressing to trivial sneering rants at Republicans often with no substance other than just pointless personal redicule.
He's losing his funny and increasingly just becoming a shallow overacting characature of himself. I also think he's became a lazyass and just showing up and going thru whatever staff writers toss in front of him. My wife won't even watch him anymore. And she used to be a very devoted fan at many levels. Again, we travelled cross country just so she could attend his DC event.
