What happened when John McCain made an appearance (not hosting, I don’t think) on SNL in late October/early November '08?
Well, Hillary has already been on this year. Just a few weeks ago, in fact. She was in a skit that made fun of trump.
And then shortly after that, Bernie Sanders was on doing an imitation of Larry David. 
I think that’s mostly true but it doesn’t really contradict what Elvis is saying, at least as I read it. Unlike GWB, Bill has been publicly and politically active in his post-presidency career, boosted in part by the legacy of a very successful presidency. He may not perform many official duties in a Hillary presidency, but this larger than life political heavyweight is going to be right there in the White House and I think it would be foolish to rule out the likelihood that his influence will run far and deep.
Wow, I just never thought I’d see “You want evidence? I got all you need, and it’s… my experience.” on this board.
I’m going to try that: “And to all of you who are yelling ‘CITE?’, I say: ‘Wake up and look around, sheeple, that’s all the cite I need!’”
You should hear her nickname for Little Bill.
