Conservative columnist calls Pennsylvanians the "R word"

From Ann Coulter's column Nov. 5 titled, "The Reign of Lame Falls Mainly on McCain":

This was such an enormous Democratic year that even John Murtha won his congressional seat in Pennsylvania after calling his constituents racists. It turns out they're not racists -- they're retards. Question: What exactly would one have to say to alienate Pennsylvanians? That Joe Paterno should retire?
