In front of 350 people at Dartmouth College in NH on Tuesday, Senator Biden was asked if he would vote to impeach the President if Bush moves to invade Iran. The Senator said yes.

"Speaking about foreign policy in Iran, Biden declared his
intention to impeach the president if he started an unjustified
war with Iran.
"The president has virtually no credibility at home or around
the world," Biden said. "People have overwhelming doubt about
his motives."
UPDATE 4:25 PM: I should point out, given that the D isn't exactly the AP, that I was in the audience for this speech (front row).
