Electoral Map in 2040-2050

What do you think the electoral map would like like in 2040 in a 50/50 race?  Meaning, what would the tossup map look like in 2040.

Of course, so many things could change between now and then, but what do you think would be the most probable shifts:  would  demographics cause the Southwest and a lot of the deep south:  AZ, TX, MS, GA, SC to trend Dem and the Midwest states like OH, MI, WI, MN, PA, IA, IL would trend GOP?

If the political divide remains similar to what it is today, I would expect something like this:

The dark colored states would hold even in a landslide for the other party.

Really, Vermont is a D-leaning swing.  The Midwest looks spot-on IMO given current trends and deunionization, but what would cause Vermont to trend to the right?  Also, ditto with Maine and Connecticut.  It seems like social issues really tilt them toward the D side.
