From NRO: "The mention of Playboy is a reference to reports that Ford attended a party thrown by Playboy magazine at the 2005 Super Bowl in Jacksonville, Florida. The issue has popped up occasionally in the campaign, most recently after Ford broadcast an ad of himself in church. The National Republican Senatorial Committee responded with an ad that said, “What kind of man parties with Playboy playmates in lingerie, then films political ads from a church pew?” Ford, who has not denied attending the event, has tried to avoid talking about it. Appearing on ABC, he said, “I’ve never been to a Playboy mansion party,” apparently referring to the famed Playboy house in California, not the Super Bowl party in Florida. Now that another ad making reference to the party, this one produced by the RNC, has appeared, the Corker campaign has released a statement saying that Corker “believes this new ad has no place in this, or any other campaign.”
