Found this on a conservative website. Interestingly the comedians aren't necessarily conservatives. Seems to be a lot of disappointment in Obama brewing.
Anyway I figure it should be a contrast from the usual kind of humor here.

Actually I thought it seemed out of character too. They are leftists, so why are they saying this stuff. There's no clue at the site. No source is given. I like the jokes though of course. They're only "tasteless" to a leftie.
Actually, I agree. I found the same jokes on other sites on a quick lookthrough without any attribution. I like the site I got them from, I like the owner, I'll have to tell her they are falsely attributed. It happens. She'll apologize.
