ABC News' Bret Hovell Reports: Sen. John McCain's, R-Ariz., campaign insists he was only kidding when he combined a Beach Boys impression with foreign policy Wednesday before a group of Veterans at a VFW hall in Murrells Inlet, South Carolina.See the YouTube video here.McCain campaign spokesman Kevin McLaughlin points out that the Senator's song was not serious and the people in the room were laughing. "He was just trying to add a little humor to the event."McLaughlin also points out that the Senator went on to express support for President Bush's pro-Israel policies and reiterated his own tough stance against Iran. McCain has long been an advocate of dealing with rogue states aggressively. Back in 2000, when then-Gov. George W. Bush was wary of nation building and talking about a foreign policy based on humility and restraint, McCain was advocating a policy of "rogue-state rollback," which he described in a 1999 speech to the Center for Strategic and International Studies as a "21st century interpretation of the Reagan doctrine." As for the light-hearted harmony, will this event portend more singing from the senior Senator from Arizona? As Simon Cowell reminds: song choice is critical.
