Well, considering the national map is tending to represent the country socially now more than ever (just look at the gay marriage map vs. whether states are more D/R than the national average since the late 90s), and the country is progressing culturally faster than ever, the GOP isn't going to have a base in 20 years unless they change.
They are the GOP, they will. Probably towards a more libertarian platform which will buy them a lot of independent votes from suburbia while they retain their Southern/white base who couldn't even think of voting for a Democrat.
Probably not anytime soon, but what makes you so sure a poor, White Southerner would favor a socially liberal, fiscally conservative GOP over a socially liberal, fiscally populist Democratic Party in, say, 50 years? I mean they did for decades after all ... (Spare me the parties switched ideologies bull.)
You're assuming most of these poor white Southerners are still fiscally liberal. I don't think most of them are anymore. I think most of them have gone so "all in" with the GOP on social issues that they've now adopted their economic theory as well.
So true. It seems like on average they are more likely to complain about how big businesses are being overtaxed and oversued...
