Here's my two cents worth. I think David Letterman and others in his profession should put a governor on what comes out of their mouths. I am not a Sarah Palin fan, in fact I think the GOP could do a lot better, but Palins children are not fair game in my opinion for any comedians funny fodder. Palin and spouse are fair game, they volunteered to put themselves out there and must be able to put up with comedians like Letterman, but not the kids. They should be off limits completely. To paraphrase a favorite juvenile battle cry, 'I didn't ask to be born', they also didn't ask to be made fun of on television or anywhere else. Leave them alone.
