Sadly, those growth areas aren't where real Democrats come from. I'd prefer a tough progressive party to the wishy-washy suburban neoliberals we're getting in the Sunbelt.
well those suburban neo liberals have kept many states blue while the working class dems have been flirting with the GOP for years. Pennsylvania is a good example, it has stayed a democratic state since 1988 thanks to Philly suburbanites consistently voting for the Dem nominee. If democrats hadn't picked up those voters, the Republican trend in western PA would have turned the whole state red.
And really, if these blue collar workers still aren't convinced that the Democratic party is the one truly fighting for them, do we even want them in our coalition?
