Charles Lindbergh getting elected President of the United States seems to be an AH cliché, especially in works depicting a fascist takeover of the U.S. and/or an Axis victory in World War II. But was such a scenario even plausible? Would Lindbergh be willing to run for President? If so, how difficult would it be for the Republicans to nominate him? (They’re the only party that would be willing to choose him.) Could he defeat FDR (assuming he ran in 1940) in the general election?
And that’s not even getting into what a Lindbergh presidency would look like. I doubt it would lead to fascism, though his antisemitism and support for eugenics could lead to some extreme policies being implemented. Since Lindbergh would have no prior political experience, he could find himself deep in over his head trying to be President.
As for foreign policy, I don’t see Lindbergh allying the United States with the Axis powers. Probably just pursuing neutrality and staying out of “foreign entanglements.” There could still be a war with Japan depending on how Lindbergh views that situation and whether or not he issues an oil embargo.
