La Follette>>>>>>>>>>>>>>>>>>>>>>>>>Coolidge>>Davis
I'd still take Davis as a second choice, albeit a very distant second choice over Coolidge. He was better on immigration.
Davis gets a bad reputation as "one of those conservative Democrats" because of his various positions on issues relating to the South, but on matters of trusts/monopolies, immigration and a number of other issues he was certainly not conservative relative to Coolidge.
This, plus Davis was opposed to the Klan, which was THE major issue of the 1924 convention, along with Prohibition.
Davis was the moderate liberal America needed at that time.
