As a market researcher, I'll preface this by saying that it's a panel from one of the worst businesses in our industry and so it's not really generalizable, but nonetheless it's kind of fun.
I suspect that there's a bit of a problem in that people may vote for their own states, which probably should be taken out of the data. As such, I figure that bigger states are amplified. I suspect that it wouldn't change the conclusions, though.
