"Palin asked for it. She should have know that they had a girl with Down's play the part. "
Correct. A more shrewd politician would have put his/her team on researching everything about the line - who said it, the show's history, etc.
This is what worries me about Palin. Remember during the campaign when she thanked a prank caller (who she thought was the President of France) when he complimented her on her Porno movie work? That kind of naivety and gullibility is something you DO NOT want in a president. You want one that sees the opponent's move 3 steps ahead. Palin is simply not shrewd. She's a fine TV analyst - but running the free world? There are better repub candidates.
