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.
Yes, and a lot of the areas that have seen pretty solid trends towards Democrats are also those areas with high immigrant populations, who in general are poorer than the average white middle class American.
