Bull Moose is a U. S. presidential election game based on the 1912 election. The split in the Republican party resulted in Teddy Roosevelt launching the Progressive Party. Concurrently the Socialists under Eugene Debs had their best showing to date. The Prohibitionists fielded Eugene Chaffin running only seven years prior to the passing of the 18th Amendment (prohibition). This resulted in a five-way race in which the Democrats actually won and the third party, the Progressives came in second.

The election is represented by a straightforward, card driven, geographically based game where the winners of each state are decided by lot. The winning of the election and victory condition criteria is loosely based on the popular vote and not on how the Electoral College actually functions.
