Lou Harris himself is a long-time Democrat. I believe that his wife is related to some prominent Democrat, but I can't remember whom, perhaps Hubert Humphrey, but probably not. I think Harris polls usually overstate Democrat strength.

ALL polls overstate Democrat strength. It's a well-documented phenomenon, though nobody has proven why. The most likely reason is sheer PC: Lots of people are still afraid to admit to others that they're conservative, but they sure pull the GOP levers in the voting booth.
