John McCain's campaign has gone through many identities, slogans, advisors and theme songs penned by liberals, but one thing has always remained constant: A campaign surrogate making headlines with his/her idiotic remarks.

There's been quite a list of McCain "gaffers" over the last 18 months, including but not limited to…

* Phil Gramm (called America "a nation of whiners" trapped in a "mental recession")

* Douglas Holtz-Eakin (claimed McCain invented the Blackberry, despite his being computer illiterate)

* Carly Fiorina (said that McCain was unqualified to manage a computer company)

* Sarah Palin (caught misstating the GDP of Namibia by 0.75% during an impromptu trade lecture to an Ohio waitress)

And now there's a new person ready to assume the duty of embarrassing McCain with his totally uninformed commentary: Joe the Plumber/Country Singer. (Who, at this point, outranks both Steve Schmidt and Rick Davis within the campaign.)

Here's Joe regarding a problem that plumbers are confronted with on nearly every house call they make: The security of Israel…

When the McCain supporter asked him if he believed "a vote for Obama is a vote for the death of Israel," Mr. Wurzelbacher replied, "I'll go ahead and agree with you on that." He didn't elaborate on how Mr. Obama, who has said his commitment to Israeli security is "nonnegotiable," would be bad for the Jewish state.

Later, during a Fox News interview with Shepard Smith, Joe reiterated his claim, putting Smith in the very un-Fox position of defending Obama.

With surrogates like Joe following in the grand tradition of Gramm and Fiorina, Barack Obama should get enough donations to stay on TV through next year's World Series as well.

Of course embarrassments run both ways. Who's to say that McCain can't return the favor by endorsing Joe's forthcoming bid for Congress with a trademark tasteless joke and a declaration that "the fundamentals of our economy are strong"?
