Texas is moving towards the Democrats?
I guess when you've reached bottom, there's no way but up. Still, I haven't seen Texas Democrats show any inclinations of moving from that position.
Your map is optimistic for Democrats, to say the least.
Yes, I made a few corrections, but the title of this thread is '25 years from now'. That's 2030. I am pretty confident the Democrats will have a bigger percent of the vote in Texas by then - but as you said, they're at the bottom now. Keep in mind also my shading - the light pink is only a very slight trend in that direction, certainly not enough to flip the state unless it is already very close.
I honestly think the far future - 20-30 years, does look pretty good for the Democrats.
