this is next to impossible considering how entrenched the republicans and democrats became at the turn of the century, but it could be done, you merely need the 2 parties to fracture enough, say in the 1912 election, as an example, both the republicans and democrats are split (wilson doesn't get nominated and runs his own third party candidacy) allowing debs to get a few electoral votes, obviously no candidate would come close to getting the majority needed, what are your thoughts?
