Let's say that Calvin Coolidge dies of an heart attack in, say, Febuary 1926. This makes Charles Dawes president. What will Dawes undertake? Any consequences for the Great Depression? If it still happens that is.
My impression of Dawes is that he was a loose canon and quite possibly would have been opposed for the GOP nomination in '28. Perhaps by Hoover. I doubt that the crash would happen earlier w/him as POTUS.
On the other hand, Dawes was a banker. One who knew how the financial systems worked. He could migitate the effects of the Depression, making it a recession instead.
I thought that too until I considered that Hoover had a business and economics/commerce background too. If Dawes won the nomination and election in 1928 would he have approached the crash of '29 similiarly to the way Hoover did? I think so.
