Glenn Beck hosts the controversial "Restoring Honor" rally at the Lincoln Memorial in August, 2010.

To believe Glenn Beck is to believe that the decline of America began not with the election of Barack Obama, but with the election of Woodrow Wilson back in 1912.

Wilson has become a target for not only Beck but for some tea party candidates like Sharron Angle, who's campaigning for Harry Reid's Senate seat.

Historian Sean Wilentz has written a big article on the Tea Party's cold war roots in this week's New Yorker. He joins Madeleine in the studio to talk about the subject of his piece in a two part segment.
