Factcheck.org

Factcheck.org is an awesome site. And I use awesome in the same context as Bush when he called the Pope's speech "awesome."

They break down the ads for you fact by fact, so you can see how the candidates are lying. Here they break down a Republican ad claiming Obama voted 94 times to raise taxes. Turns out some of those votes were for things like helping Hurricane Katrina victims, or raising the minimum wage.

They catch Obama polishing his resume a little here. Obama's ad says, "That's why I passed laws moving people from welfare to work, cut taxes for working families and extended health care for wounded." Factcheck.org points out that it would be more accurate for him to say that he "helped" pass laws, since one of the bills wound up not even having his name on it. Still he was involved with initiating those bills, and they did what he says they did - so if that's the worst thing they can catch him at - it's not bad compared to the outright lies they've got on McCain and the GOP.
