The election of 1924 was a sweep for Calvin Coolidge, but it was under the shadow of a major personal tragedy. A blister of his son turned into blood poisoning, and Calvin Jr died on July 7. The normally silent Cal openly wept and he was never the same afterwards. Let's say that this tragedy happens a couple months earlier, when who would get the Republican nomination wasn't as certain. Calvin Coolidge ends up declining to run due to his emotional turmoil. Who would be picked instead of him? Given how easily Coolidge won, I have little doubt the Republicans would win in 1924. What would that candidates' potential presidency be like, especially if they end up running a second term and are in office in 1929
