Right after the November 1932 election, while Hitler was angling to become chancellor, the Social Democrats and the Communists could (according to my model) have struck a deal with the Catholic Center Party, depriving Hitler of the two-thirds majority he needed. To do so, however, they would have had to move meaningfully in the direction of the Catholic Center Party’s policy desires, perhaps so much so that a member of the Catholic Center Party would have become the chancellor instead of Hitler.
