The GOP is more at risk of oblivion. The civil war between the white working class and corporate class is in suspension right now, but will explode with neutron bomb force if Trump loses 2020/the next time they're out of power.
Add demography on top of that and a changing economy (the biggest bomb of them all) and here is your new Democratic majority coalition -
1. College educated whites
2. Latinos
3. Blacks
4. Asians
They will probably be in sufficient force in 2024 for the Democrats to rule for quite some time.
LOL, DONALD TRUMP won college educated Whites, and Republican House candidates won them handily. Good luck with this wet dream.
48-45%. 44% also voted for the House Democrats. I know you want to believe your “white permanent majority“ here but it isn't.
No party will ever have a permanent majority, but in the short term it seems more likely that college whites return to the GOP than it does blue collar midwesterners returning to the democrats.
