Blogger Marshall Wittmann, a McCain Republican turned moderate Democrat, notes that pandering to the tinfoil-hat crowd carries dangers beyond a reinvigorated GOP base:

Will the American people have faith in and trust a party that claims that it was gullibly duped, or as George Romney claimed about another war--that it was "brainwashed"? Moreover, should the objective be re-fighting the reasons to go to war and making the Democrats the official anti-war party or should the goal be achieving reasonable success in Iraq? If you believe in the former than you would encourage more efforts like the one Senate Democrats undertook yesterday. If you believe in the latter, you want the opposition party to present a better plan for winning this war.

While the war is increasingly unpopular, the Democrats should be careful that they are positioning themselves as a party that is gullible, feckless and indecisive on national security.
