Who thinks Joe the Plumber was a plant?

I remember thinking watching the video a couple of days ago that he seemed less interested in Barack's answer than goading him. He happens to be buying a business that makes $250,000 a year, coincidentally Barack's cut-off for tax policy rates, and as soon as Barack's talking he looks bored and is faking interest.

Now that McCain clearly zeroed in on that (who knew he used Youtube?!) and dwelled on it so long, I'm convinced.
