Pretty much in the title, looking into research for a new TL I'm planning to write and several events taking place has Roosevelt winning a third term and the US entering the War early, giving the Allies a boost needed to win the conflict roughly a year earlier than OTL.
Following that in TTL, the US would be caught up in an occupation of Mexico to prop up a puppet government formed by an even more chaotic Mexican Revolution, a deeply unpopular move. Due to this, the Republicans would be voted out of power and a divided Democrat Party, torn between those wanting to turn back the clock on the Progressive legislation introduced by the previous government, and those wanting to build on it. This division leaves the Democrats without any great political will for sweeping change and the economy is left to its own devices.
Would this result in the Wall Street Crash, or something similar to it, happening in the same time frame as OTL at all?
