Don't underestimate the power of Fox News Channel or one of their top-rated hosts, Glenn Beck. Because according to the latest Democracy Corps poll from Democratic consultant James Carville and pollster Stanley Greenberg's, they're responsible for firing up the Tea Party movement.

Says their latest poll release memo: "The Tea Party is a grassroots, intensely ideological, conservative Republican movement, fired up by Fox News and Glenn Beck. It is not remotely an independent or populist revolt against the elites or a working class revolt rooted in frustration with the recession, Wall Street, and government."
