Nope. The areas of these states that are moving left are actually the richer areas. NoVA, suburban Denver, suburban Charlotte, South Florida, Cincinnati, etc. These voters are being turned off by the Tea Party and Republican populism.
For the last time, richer areas =/= richer voters. And liberal =/= left, especially when talking about elite liberals.
Exactly. For example, like 8 of the 10 "richest" states are blue states, but the richest voters in most of those states (by income) still go Republican.
