Another from 1980, Reagan won Alabama
Clear pattern here: Reagan won narrow wins in many Southern states off basis of big wins in heavily white exurban wealthy counties.
Cumulatively, Carter had a Trump-sized EC bias in his favor in 1980. Reagan had to win nationwide by 3ish to take the EC.
Nope the Tipping Point State was 1.81 points to the left of the nation in 1980 while in 2016 it was 2.86 points to the right and in 2020 3.82 points to the right.
Even Obama's advantage in 2008 is bigger where the tipping point state voted 2.25 points to the left of the nation.
