Makes a lot of sense. What I'm seeing in Virginia, not just recently but from past history is that most voters these day seem to follow family/regional lines. Going back to at least 1968, if not before the trend seems seems to be "my family has always been ______> so I'm voting ______.
I mention 1968 or more probably 1972 because that's when the Southern (Old time Confederate leaning Democrats "got religion" and started voting Republican. Partially thanks to George McGovern as the Presidential candidate, still some fallout with 1968's Democratic Convention riots and a popular "Democratic" Governor who made his return as a Republican.
Very little has changed with the exception of what was once rural exurbs have slowly become suburban suburbs. The most "conservative" of the bunch still want lots of farmland and trees, and the Damn Yankees and halfbacks keep moving in. A lot of the "farmland" has basically been abandoned (Heirs that have moved on and have no desire for the property) And newcomers who wan the convenances of more populous areas (giant grocery stores and such)
