"This RNC ad is referring to Harold Ford attending a party at the Playboy mansion."
Actually, no, it isn't. Ford attended a party thrown by Playboy during a bowl game in Florida. Ford tried to get all Clintonian and denied attending a party at the Playboy mansion, which is true. But he did attend a Playboy party.
I think this is exactly why the Dems are whining about this ad. Ford also claimed to be a lawyer in one interview, and he's not. He did go to law school, but he never passed the bar, which is required before one actually becomes a lawyer.
Clintonian parsing of the truth isn't popular with a majority of Americans.
