We'll see if Republicans can dig themselves out of the hole. But @JoeNBC is right on the central point: the 2020 electoral college map looks exactly the way you would expect based on demography: GA, NC, & AZ as the new bluish states; OH & TX next. FL the exception due to Cubans. https://twitter.com/JoeNBC/status/1326836543944843265
To those who roll their eyes at TX ever going blue: In 2000, GWB won Texas by 21%. 2004, 23%. 2008, McCain won TX by 12%. 2012, Romney by 16%. In 2016, Trump won it by 9%. In 2020, he won it by only 5%. We are only a couple cycles away, unless something changes.
Now, that change could be better performance by Republicans among Latinos and other minorities! But that is not the *current* GOP coalition, even with Trump's 2020 improvement on his weak 2016 numbers: https://www.forbes.com/sites/theapothecary/2020/11/09/no-trump-didnt-win-the-largest-share-of-non-white-voters-of-any-republican-in-60-years/
The point of talking about demographics is not to say that Republicans are doomed no matter what. It is to say that Republicans are doomed if they don't do a better job of appealing to non-white voters. And by "better" I mean meaningfully better than Trump did this month.
