Tucson has always been heavily Hispanic and Democrat-and a college town, the land of Udalls, Deconcinis, and Rondstats. In fact Arizona was a Democrat state until the 1960s
“Tucson has always been heavily Hispanic”
Maybe in your memory but not in mine. Nor my parents who were there from the ‘30s on.
PS your list is missing some rather famous names:
Goldwater, Fannin, Williams, Pyle, Greenway...
And the old Democrats in Arizona were mostly Southern Democrats like Waldon Burr. The Udalls just piggy backed on that and still do. Their “liberalism” is just Mormon reaction to traditional American conservatism.
Late model Rats were more like the Babbits and Deconcinis.
