I found this quote on another political website. (And if it's inaccurate, my apologies. Some casual googling found other sites also highlighting this quote.)
From a stop in NH last week, Hillary said, ...
... "If the most important thing to any of you is choosing someone who did not cast a vote [to authorize the war] or has said his vote was a mistake, then there are others to choose from."
Sweet, thanks for making the choice so simple! Now I know to shop my primary vote elsewhere. If I wanted a president who didn't think this war was an unmitigated mistake... then I guess I would have voted for Bush.
