Why the 1920 US president cannot be projected confidently

Who would be president of the United States in 1920 if the First World War were delayed?

It cannot be projected confidently; Wilson historically served until March 1921, but the missing war would change the political path that kept him in office.

Woodrow Wilson historically remained president until March 1921, but that does not make him a safe choice for this counterfactual. His political position depended partly on a wartime record that disappears if the 1914 conflict is delayed. Electoral politics can then branch in ways that are harder to constrain than naval development, where fleets still answer persistent missions, budgets, and technologies. The most defensible conclusion is that the 1920 presidency cannot be projected with confidence.
