For some cute games, like Gaffe Gunner Joe, check out Politico. [OMG, I did better as Sarah Palin shooting down the pigs in lipstick than I did as Joe Biden shooting the feet in the mouth.]
And for some debate fun, dowload McCain Lying Bingo Boards from Pinocchio Politics. They're not as funny as the Palin Bingo cards, but they contain good factcheck statments and can also be used when canvassing door to door or at campaign parties. The squares contain lies McCain has told about Obama (such as: Obama wants to teach sex ed to kindergartners) along with a factcheck statement (Actually, the bill Obama voted for in the Illinois Legislature helps protect children from sexual predators).
