And who else they voted for in 1952, 1956, 1972, and any other election you think they would be able to vote in.
This is so weirdly specific I feel like taking a stab at it. Is it someone you know? (just curious, feel free to disregard)
German-American farmer (or entrepreneur connected to farming in a tangible way), somewhere on the northern Plains... probably in one of the Dakotas. Devout Catholic. Very proud of their German heritage, probably bilingual or even speaking German as a first language. Sensitive to perceived discrimination and vulnerable to market swings. Populist authoritarian with a judgemental, moralistic streak at times; registered Republican who despises Wall Street.
1940 (first eligible election): Willkie
1944: Dewey
1948: Dewey (liked Truman though)
1952: Eisenhower (of course)
1956: Eisenhower (was tempted to vote Stevenson or leave the ballot blank but... it was Ike!)
1960: Kennedy (half-ashamed and half-proud, to vote for this Democrat who was also a Catholic)
1964: Goldwater (people said he was crazy but he talked about the banks)
1968: Humphrey (had some wacky liberal ideas but was a good Midwestern guy, good for the farmers)
1972: McGovern (see above)
1976: Ford (didn't trust that hypocrite Carter with his Playboy moralizing)
1980: Reagan (knew something was up with Carter and sure enough, he destroyed the Plains economy)
