Correlation between earning disparity, and voting.
I found this amazing blurb in the latest issue of The Atlantic:
"… rich people in poor states are much more likely to vote Republican than rich people in well-off states… as a state’s average income rises, the correlation between being wealthy and voting Republican disappears. In Connecticut, for example, there is almost no connection between income and voting behavior: both the poor and the rich tend to vote for Democratic candidates."
Maybe it’s just me that finds that a bit amazing, but I think it says a lot about the platforms of the two major parties.
