You can't turn a red state blue by moving wealthy people into it. There's not enough of you. Only 9% of Americans make over 100K a year. Only 2% make over 200K.
Isn't this what is happening to Virginia? The Northern Virginia area has started to overpower the other 90% of the state politically and is turning it blue.
In PA the 2016 presidential elections went Trump by roughly 1% of the pop (~50K votes). That is roughly the number of employees Amazon was floating during their HQ2 search. Some minor demographic shifts could easily account for a 50K swing. As another example, NC elected a democratic governor by 10K votes. These are slim margins that can drastically tip the balance of power in local and federal politics!
