Nixon/Lodge in 1960
That's a lot of electoral votes and popular votes you show going to Robertson and Faubus third party. More than Teddy Roosevelt got in 1912, 88 EV, 17% PV, and more than George Wallace got in 1968, 46 EV, 9% PV. That would easily make this 1960 third party the most successful third party in U.S. history. Nonetheless a very interesting map. It could have happened I suppose.
In your map, JFK would still become President, as I believe the Democrats controlled the House in 1960. Correct me is I'm wrong.
i think faubus was at his peak in 1960. he had just gone through the episode with little rock central high school and (sadly) that made him a hero among many southerners.
also, i think most southern democrats still basically despised humphrey in 1960. wasnt it after his speech at the 1948 democrat convention that the southerners walked out?
yes, democrats controlled the house in 1960. BUT a lot of their numbers came from the south. so, who knows how those representatives would have voted
