Fair enough. Honestly, I haven't seen Joe rip Trump since he got the nomination. I may be wrong (wouldn't be the first or last time). What bothers me is to see these conservatives line up behind Trump, eager to ignore all of his warts, while nitpicking the hell out of guys like Ryan. I understand the frustration with Ryan to some degree, but I still think he's one of the few bright spots in the Republican party.
Probably because he lost all will to oppose Trump once his opponent was Hilary. At that point it could basically be anyone short of Vitterd and he is going to support the person to beat her.
He isn't really cheerleading him, he just knows he has no choice but to support him or watch the world burn an eternal flame.
