He's a registered Republican, who appears to have voted in the Ohio primary (in which most Republicans apparently stayed home or voted Democratic because McCain was unopposed), and (and this is the best part) he's 'closely related' to Robert Wurzelbacher, son-in-law of Charles Keating, and former VP of Lincoln Savings and Loan parent company American Continental. I'm sure we all remember Charles Keating.
Steve Schmidt is supposed to gone ballistic as soon as he heard the guy's name. So I can actually believe this was not a plant at all.
I'm just dying to hear Joe the Plumber spin about how he really was undecided, and he really wasn't just pretending to be an independent to sucker Obama into pandering to him. Instead of giving him a detailed and honest answer to his question.
(It's so easy to forget just how damn good Sammy Davis and Gregory Hines were. Joe's got some serious shoes to fill.)
