Who's the plumber?

Joe the plumber from Ohio got more air time than Iraq last night at the presidential debate. He doesn't look like the Joe Six Pack we pictured. McCain used him to bludgeon Obama on tax policy, declaring it was a bad time to raise taxes on anybody. Obama turned it around to point at McCain's dangerous and ill-advised health care plan, and his support for taxes cuts for the uber-rich. (Though as McCain noted, Joe the Plumber is no Warren Buffett.)

So who is the real Joe the Plumber?

Here are a couple of links to read about him.
