That only works if one presumes the "purple" areas are like Mittens, Woke Libertarians. The facts remain, that whilst popular in elite circles, most of those areas are closer to AOC and Sanders in economics; the core divisions are the fact that these areas also tend to be socially very conservative and thus selling them on transgender children, atheism and abortion won't do well, nor will "Shame on you whitey" since a lot of those areas have lots of White poor people.
The failure here is the assumption that Neo-Liberalism is some kind of wise center or the common way of thinking of most. It is an elite opinion and worldview that is radically overrepresented in media, but in the wild it is rare.
I'd even say the ones here are probably just LARP'rs.
