That's just starting a new liberal city in the middle of Trumpistan. It'll be like Austin or Atlanta even if everything goes perfectly.
I say we get a few California and New York billionaires to just buy a small shithole town in rural Appalachia or Louisiana or something. Give every resident $70k a year, for free. Free healthcare, college, job training, for life. Fix up their houses and their infrastructure. You could probably do it all for just one billion dolllars. And slap banners everywhere saying COURTESY OF THE US DEMOCRATIC PARTY.
Shower these dumb fuckers with cash so they'll shut up about the culture war shit. And then in a generation when their kids are educated, they'll be normal, non hate filled people.
