Amazing.
He wasn't a U.S. senator in 2003 and therefore could not vote against the Iraq war.
Big-ears wasn’t sworn in until 2005. He has only been a Senator for a little over 3 years and over a year of that has been spent campaigning for POTUS.
Clarification: BHO wasn't a senator in 2003. He didn't vote for crap. He just says he was always against the war.
