The National Post’s Jonathan Kay is not a liberal. He attended the Tea Party Convention in Nashville, Tennessee, and filed this report for Newsweek: Tea Party Movement Is Full of Conspiracy Theories.

(I know. I’ve only been trying to point this out for the past year.)

After I spent the weekend at the Tea Party National Convention in Nashville, Tenn., it has become clear to me that the movement is dominated by people whose vision of the government is conspiratorial and dangerously detached from reality. It’s more John Birch than John Adams. …

One of the most bizarre moments of the recent tea-party convention came when blogger Andrew Breitbart delivered a particularly vicious fulmination against the mainstream media, prompting everyone to get up, turn toward the media section at the back of the conference room, and scream, “USA! USA! USA!” But the tea partiers’ well-documented obsession with President Obama has hardly been diffused by their knack for finding new enemies. …

I consider myself a conservative and arrived at this conference as a paid-up, rank-and-file attendee, not one of the bemused New York Times types with a media pass. But I also happen to be writing a book for HarperCollins that focuses on 9/11 conspiracy theories, so I have a pretty good idea where the various screws and nuts can be found in the great toolbox of American political life.

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.

This world view’s modern-day prophets include Texas radio host Alex Jones, whose documentary, The Obama Deception, claims Obama’s candidacy was a plot by the leaders of the New World Order to “con the American people into accepting global slavery”; Christian evangelist Pat Robertson; and the rightward strain of the aforementioned “9/11 Truth” movement. According to this dark vision, America’s 21st-century traumas signal the coming of a great political cataclysm, in which a false prophet such as Barack Obama will upend American sovereignty and render the country into a godless, one-world socialist dictatorship run by the United Nations from its offices in Manhattan.

Sure enough, in Nashville, Judge Roy Moore warned, among other things, of “a U.N. guard stationed in every house.” On the conference floor, it was taken for granted that Obama was seeking to destroy America’s place in the world and sell Israel out to the Arabs for some undefined nefarious purpose. The names Jeremiah Wright and William Ayers popped up all the time, the idea being that they were the real brains behind this presidency, and Obama himself was simply some sort of manchurian candidate. …

And then, of course, there is the double-whopper of all anti-Obama conspiracy theories, the “birther” claim that America’s president might actually be an illegal alien who’s constitutionally ineligible to occupy the White House. This point was made by birther extraordinaire and Christian warrior Joseph Farah, who told the crowd the circumstances of Obama’s birth were more mysterious than those of Jesus Christ. (Apparently comparing Obama to a messiah is only blasphemous if you’re doing so in a complimentary vein.) To applause, he declared, “My dream is that if Barack Obama seeks reelection in 2012 that he won’t be able to go to any city, any city, any town in America without seeing signs that ask, ‘Where’s the birth certificate?’”

Many of the tea-party organizers I spoke with at this conference described the event as a critical step in their ascendancy to the status of mainstream political movement. Yet with rare exceptions, such as blogger Breitbart, who was reportedly overheard protesting Farah’s birther propaganda, none of them seems to realize how off-putting the toxic fantasies being spewed from the podium were.
