You will notice the vast gulf between how Palin operates and how Karl Rove and the blissfully incompetent Bush Public Relations operation during the Second Term? Notice a difference?
One fights back and NEVER lets a negative attack go unanswered, indeed, one uses lefty mistakes and miscues against its opponent, the other's meek responses gets buried in an avalanche of left wing propaganda.
You saw the difference today. ANY potential candidate who knows how to counterattack like that is showing you Presidential timbre.
Period. Accept no rationalizations.
Best,
