Has Joe the Plumber passed his use by date?

Sure looks that way when he starts getting grilled on Fox News Channel. Granted, it's unlikely Sean Hannity would have treated him the way that Shepard Smith did, and Bill O'Reilly only would have done so if he figured he needed one of those stories to demonstrate that he really isn't a partisan. Smith seemed incensed at Joe's assertion that a vote for Obama is a vote for the death of Israel and wouldn't let him off the hooks. Kudos to FNC for committing journalism.
