Too much slime, even for a pitbull?

The Rovian slime machine has already proven far too much for Colin Powell, who has thrown his weight behind Obama, and John McCain himself has shown his discomfort at some of the negative emotions stirred up by the Republican Party campaign.

So who's the latest to express disquiet at Republican tactics... Sarah Palin.

Um. When the "pitbull in lipstick" starts second guessing the smears, it appears that even the Republicans have realised that Republican tactics are rather unpalatable to the US public...
