There are some dirty tricks, and dubious practices in all elections, but this one takes the biscuit. The Republicans in Pennsylvania sent an appalling email to voters, telling them that voting for Obama would cause a second holocaust, and that Obama directly told Acorn to commit voter fraud.
Now they've been caught, they're claiming it wasn't authorized, tho the person responsible say it was. I notice however, that they are not exactly promising to re-email all those who received the original email, strenuously refuting the contents and apologizing...
