The membership of the Socialist Party approved the 1934 Declaration of Principles in its referendum vote, a victory which moved the Old Guard towards the exits—although factional fighting into 1936. The leaders of the Old Guard formed a new rival organization to the Socialist Party, the Social Democratic Federation in 1936 and somewhat reluctantly endorsed Franklin D. Roosevelt for President in the election of that year. They also worked to establish the American Labor Party (ALP), a labor-oriented umbrella organization that included both socialist and non-socialist elements, putting forward both its own candidates as well as endorsing those of the Democratic and Republican parties.
