I see the McCain campaign has taken on a foreign policy adviser. Joe really is a renaissance man.

Joe Wurzelbacher, a.k.a. "Joe the Plumber," on Tuesday twice agreed with a claim from an audience member at a John McCain rally that "a vote for Barack Obama is a vote for the death to Israel." 

Wurzelbacher was hitting the campaign trail on behalf of McCain for the first time, joining former Rep. Rob Portman on a GOP bus tour through Ohio. 

At a stop in Columbus, he fielded the question on Israel from a self-identified Jewish senior citizen. 

The questioner said he was "concerned" with Barack Obama’s associations and "It’s my belief that a vote for Obama is a vote for the death to Israel." 

Wurzelbacher responded: "I do know that." 

The questioner then complained about Obama’s tax policies and reiterated his Israel comment. 

"Well, you know what, I’ll actually go ahead and agree with you on that one," Wurzelbacher said. "You know … no, I agree with ya.’"
