The 2020 Election was one defined by Polarization by Education, As such Taking a look at the levels of Education by D/R Margin may give us some insight as to where states are Trending.
Looking At Education we find a few groups of interesting states
Education suggests a Dem Lean/GOP White Strength(NE UT KS & MT)
Heavy Dem but Rates don't suggest they'll fully leave the Dem Column(ME, DE)
African Americans Dem Strength Blue (MD MI PA)
African Americans Dem Strength Red (MS & LA)
Latino & Other Dem Strength Blue (NV CA HI AZ PR* WI & AZ)
Republican Rural Strength(SD ND TN ID WY AL OK MO & KY)
Wrongfully Considered GOP Reach(RI NY & IL)
On Line or Almost on the line(AK SC OH IA TX FL NC GA IN AR)
Too Democratic by Demographics & Education(WA & VT)
"Dem Trending" Suburbs(MN NH NJ VA CO CT)
Here we can clearly Identify certain Trends and Potential Trends, The two that should be hilighted are 1) The Dem's Latino/Other strength holding many states above what Educations Splits suggest they would be & 2) the Dem Lean by Educated but actually Republican States.
The reason that these two sets of states should be hilightedd are because they are the ones most likely to snap in the direction of the opposition party. How likely this is is up to psephologists to determine in each election cycle, but if any "safe" states were to vote for the oposite party these would be the ones people should look at for potential suggestions.
