WORKING CLASS WHITES! Haha, seriously, the GOP is still strongest in the Plains and upper Mountain West, and that includes dominating the EDUCATED and SUBURBAN areas in those states. That won't change.
There is nothing that suggests that AR and KY are still "Democratic states at heart" or some garbage like that. WY and ID could at least trend or become D if there are major demographic changes or weird migration patterns in the next decades. Keep in mind that these states aren't very populated, so you're more likely to see a VT 1992 redux here than in states like AR or KY.
Also, nowadays the GOP is just as strong in KY/TN/AR as it is in the Plains and WY/ID, whether you like it or not.
The states south of the Mason-Dixie line have historically been subject to much larger swings and populist movements. The interior plains have not had this kind of history. It would make sense to expect the interior plains to continue their long GOP streak.
I'm not so sure about that. In 1960, Vermont had never voted democratic, and Mississippi republican. Now they have for 7 elections straight. It's not out of the question that Democrats could capture the plains.
