The south was way too brutal to McGovern to count. He got like -I think- 19 percent in Mississippi
McGovern lost Mississippi 78.20-19.63%. Mississippi actually went more strongly for Nixon than Washington D.C. went for McGovern. And Nixon got more than 70% of the vote in Alabama, Georgia, South Carolina, and Florida as well (in addition to Oklahoma and Nebraska). But in other respects, 1972 was pretty much a universal rejection of McGovern. McGovern lost by at least 5% or more in 49 states, and in 45 states (all except for Massachusetts, Minnesota, Rhode Island, Wisconsin, and South Dakota), he lost by double digits. He won the fewest number of counties of any major-party presidential nominee since the Civil War.
Yeah, which makes McGovern's margin in Massachusetts the biggest wonder of my life
