This would be my map of state trends I am pretty confident in right now:
Save for a few exceptions, this map still seems pretty accurate. Adding to this, I would color SD, PA, MN and AR blue and CO, LA, AL, SC, MD, UT, MA, KS and OK red.
Possible 2032 map with the incumbent D winning reelection?
I doubt Dems will get all the way to 70% in CA (I expect some erosion in NorCal as more and more Dems outside of CA are starting to run against Silicon Valley, which will counter continuing Dem movement in SoCal and keep things in the low 60's statewide) or that they will stay that strong in New England at the same time they are winning the entire Deep South, but the general theme of this is plausible.
You think the entire Deep South would give out in a presidential race before KS? I think KS would go first unless the Dem president is running an explicitly religious left campaign. OK might even flip before AL does.
