I see FDR got 60.8% popular 1936. Slight edge.
-—the widest popular vote margin in any presidential election.-—
” winning 60.7 percent of the popular vote and 520 electoral votes, to McGovern’s 37.5 percent and 17, respectively.
In becoming the first Republican ever to sweep the South, Nixon received nearly 18 million more votes than McGovern. He still holds the record as having achieved the widest popular vote margin in any presidential election.”
It astounds me that the South was his base, and New England was his least popular region.
