The Sheehan Effect? Tapped's Garance Franke-Ruta flags a new ARG poll that shows Bush's approval rating has plummetted to an astonishing 36 percent -- down six points from a month ago.

Update: A reader notes that the recently reliable Rasmussen poll (which almost precisely forecast the 2004 presidential vote) shows Bush at a far healthier 48 percent, which is up five points from early last week. (That's right around when the conservative anti-Sheehan backlash really got rolling, by the way.)

Incidentally, Rasmussen also shows that Americans aren't too crazy about Cindy Sheehan, and that nearly four in ten (and a clear majority of Democrats) think it's time to bring the troops home.
