As it seems the gap between the haves and the have nots is a Democratic talking point?The Rich Are Different From You and Me
What makes a red state red, and a blue state blue? It’s the voting habits of their wealthiest residents, according to a study from Columbia University. Although the GOP has traditionally been considered the party of the wealthy and the Democrats the party of the poor, lately Republicans have tended to win in the poorer states in the interior of the country, while Democratic victories have been concentrated in the wealthier states along the East and West Coasts. This trend has led pundits to argue that the Republicans have developed a common touch, while the Democrats have become elitist and alienated from the masses—but actually, the study’s authors argue, the red-blue gap is best explained by the fact that rich people in poor states are much more likely to vote Republican than rich people in well-off states. In Mississippi, for example, there is a strong relationship between income and voting patterns: the wealthier the Mississippian, the more likely he or she is to pull the lever for a Republican presidential candidate. But as a state’s average income rises, the correlation between being wealthy and voting Republican disappears. In Connecticut, for instance, there is almost no connection between income and voting behavior: both the poor and the rich tend to vote for Democratic candidates.
