Reporting for Newsweek from the Tea Party convention in Nashville, author Jonathan Kay (“I consider myself a conservative”), paints a rather damning portrait of the movement:

Within a few hours in Nashville, I could tell that what I was hearing wasn't just random rhetorical mortar fire being launched at Obama and his political allies: the salvos followed the established script of New World Order conspiracy theories, which have suffused the dubious right-wing fringes of American politics since the days of the John Birch Society.

And behold the wonder here [emphasis added]:

Perhaps the most distressing part of all is that few media observers bothered to catalog these bizarre, conspiracist outbursts, and instead fixated on Sarah Palin's Saturday night keynote address. It is as if, in the current overheated political atmosphere, we all simply have come to expect that radicalized conservatives will behave like unhinged paranoiacs when they collect in the same room.

Amen to that.
