Did you see the vote totals for South Carolina and Mississippi in 1936 ?
South Carolina was 99% for FDR (114,000 votes to Landon’s 1,646 — and Landon ran on two separate tickets !).
Mississippi was 97% for FDR (Landon got just over 4,000 votes and 2.74% — the Socialist Party candidate Norman Thomas got the remaining .2%).
Those states were more Democrat than some precincts in Detroit are today.
Mississippi or S. Carolina Democrats were conservative 1936. Perhaps this explains Vermont's result too.
Anyway I love to understand American History through Elections and Votes.
