The party was divided into two main factions. The conservative faction led by Congressman Victor L. Berger of Milwaukee promoted pragmatic democratic reform, fought corruption, and opposed immigration as both a wage suppressant and drain on public resources. The radical faction sought to overthrow capitalism, tried to infiltrate labor unions, and sought to cooperate with the Industrial Workers of the World (IWW or "Wobblies"). It supported immigration to increase ranks for the war on capitalism. With few exceptions, the party had weak or nonexistent links to local labor unions.
