Question

Ultimately, how did President Wilson contribute to the failure of the Treaty of Versailles to pass in the Senate?

Answer 1

The closest the Treaty came to passage was on November 19, 1919, as Lodge and his Republicans formed a coalition with the pro-Treaty Democrats, and were close to a two-thirds majority for a Treaty with reservations, but Wilson rejected this compromise and enough Democrats followed his lead to permanently end the chances for ratification.
