Would McMath do better or worse than his VP in OTL?
About the same. The 1952 election was a combination of Democrat Fatigue and Liking Ike a LOT. Eisenhower was the most genuinely heroic nominee for President in the 20th century. He was the military leader of the Allies. How big is that? He was well-liked and he was very non-controversial. He won the Great War. I don't know if either party could find anyone with the kind of National stature that Eisenhower enjoyed in 1952. People liked Ike, and for sound reasons that they could articulate.
