Turns out that Joe the Plumber is actually not a plumber (licensed one anway), has a lien against him for failing to pay his taxes (maybe explains his opposition to taxes), is not an undecided independent (registered as a republican), hates social security (http://www.talkingpointsmemo.com/archives/237630.php) and may even have an indirect relationship to Charles Keating and Savings & Loan Scandal (I am not asserting this last one as fact - but here is the link:
