It's not exactly clear why the folks at Tea Party Express are buying up so much ad space on Fox News these days. They could save themselves a whole lot of money by just waiting for Glenn Beck and Sean Hannity to their inevitable "reports" on the event and do the publicity for free.
Of course, said reportage will emphasize the current Fox narrative -- that these teabaggers are just a bunch of "ordinary Americans" who happen to be easily inspired by hysterical right-wing propaganda. What could be more "grassroots" than that?
Incidentally, this "Tea Party Express" event is being sponsored by the "Our Country Deserves Better" PAC, an offshoot of Move America Forward. It's chaired by Howard Kaloogian, the erstwhile Republican congressional candidate from California.
