GOP will continue to make gains with rural WWC voters, especially if they embrace Trumpist populism over billionaire donor neoliberalism (not certain they will). At the same time, not having Trump's personal baggage will help them in the suburbs, especially among women.
Serious question, for both the Trumpists and Democratic partisans who love the idea of this trend continuing ... just how many of these voters do you think there are left to flip in states that matter, and just how long do you think the GOP can rely on that and win??
My answers, personally, are not many and not long.
I'm not either of those things but:
1) A decent chunk in the Midwest and New England.
2) Not long at all barring a lot of "events" happening.
