Suburban gains: Demographic Change or Newly Liberal Whites

[GALeftist]

This is anecdotal, so take it with a grain of salt, but at least in my experience I've seen a massive swing in these affluent white Romney voting types. Back in the day, being a Democrat was sort of viewed as quaint or maybe even admirably idealistic, but it was generally accepted that voting for Republicans was the "responsible" thing to do. Now, though, saying that you're a Trump supporter will make those people think you're an idiot, and even saying that you're a Republican will raise some eyebrows, so a lot of people are a lot less vocal about their beliefs outside their immediate family. Buckhead-type whites really have never wanted to be lumped in with rural Georgian whites, who they often perceive as unintelligent and backwards, and for better or worse Trump has tied himself to that group of people.

Also, their children are in general pretty liberal, especially the women.
