Okay, this is my last WI today, I promise. I'm thinking of doing another TL, and I'm trying to test out the water, as it were. One of my ideas is that Roosevelt does much better in the 1912 presidential election--not good enough to win, mind, but good enough to definitively establish the Progressives as a powerful party.
Is it possible and how would one do it? I'm imagining a Progressive-Socialist alliance helping out here.
