I love the part about Larry David. I, too, think Curb Your Enthusiasm is a witty, intelligent show that plays to conservatives well by showing how silly political correctness is and how much trouble Larry gets into for no reason just because he doesn't play games. I've also wondered why, apart from the way he was probably raised and his Hollywood affiliation, someone so uncorrect in his humor could be a lib.
The real Mrs David is a big-time enviro-whacko. Maybe Larry's liberalism goes only so far as his wife.
I may be wrong but I think the overwhelming majority of Jewish men Larry David's age are Democrats. Brought up by FDR-loving parents. First favorite politician was JFK.
I got the Seinfeld DVD's for Christmas and in one episode, a deleted scene has Jerry ripping the National Organization for Women. It didn't quite fit, so I can see why it was cut from the show, but it was a pretty good comment.
