I found this site recently, and it's worth looking at or even bookmarking. It's pretty in depth into President Obama's campaign promises and sorting truth from fiction.
PolitiFact is a project of the St. Petersburg Times to help find the truth in politics. Every day, reporters and researchers from the Times examine statements by members of Congress, the president, cabinet secretaries, lobbyists, people who testify before Congress and anyone else who speaks up in Washington. They research their statements and then rate the accuracy on their Truth-O-Meter – True, Mostly True, Half True, Barely True and False. The most ridiculous falsehoods get their lowest rating, Pants on Fire.
They also rate the consistency of public officials on their Flip-O-Meter using three ratings: No Flip, Half Flip and Full Flop.
