Why would Heinz-Kerry stop in Kansas anyway? There are no electoral college votes for a Rat there. Never have been ... never will be.
You're right...KS has never voted Democratic for POTUS, except in 1912, 1916, 1932, 1936 and 1964.
They also have a (D) governor, and have several times in the not-too-distant past as well. That said, a (D) governor in Kansas isn't anything like one in, say, Massatoosis.
