Communist Party Votes by States and Counties 1922-1946

The Communist Party devoted energy and resources to electoral campaigns starting in 1922. Party leaders did not expect to win, but they expected members and followers to support the ticket. Election tallies thus provide an indication of how many voting age citizens were loyal Party supporters in any year and place. Communist candidates were able to win about 100,000 votes in several elections during the 1930s and in Senate races in 1940 topped 115,000. These figures may serve as best estimates of the numbers of CP loyalists during party's heyday. The maps and charts show the geography of party strength, detailing the number of votes for Communist Party candidates for each county and every electoral contest from 1922 to 1946. Sources are explained below along with brief notes about CP electoral strategies and challenges. The maps are hosted by Tableau Public and may take a few seconds to respond.

Notes: Communist candidates appeared under several party labels in the 1920s, including the Workers Party of America. Many states refused to list Party candidates on their ballots, especially in the South where Party membership was weak in any case. But ballot access was also an issue in California before 1934, in Illinois after 1932, and Ohio after 1936. The CP lost ballot access in other states after 1941. Strategy shifts also affected what we see in these maps. Pursuing Popular Front alliances beginning in 1936, the Party supported progressive Democrats in many races in 1937 and 1938 but returned to its go-it-alone stance in 1940 in the wake of the Hitler-Stalin pact, running candidates wherever feasible. After the 1941 German invasion of the Soviet Union, supporting progressive candidates again became the priority. The Party offered only a few candidates for Congress or the Senate in 1942 and thereafter ceased running independent campaigns for federal and statewide offices, resuming in 1964.

"We Charge Genocide"
: The 1951 Black Lives Matter campaign of the Civil Rights Congress

More than sixty years ago, the Civil Rights Congress, affiliated with the Communist Party, engaged in a campaign to hold the United States accountable for genocide against African Americans. We map 152 incidents that the Civil Rights Congress offered as evidence in support of this claim. These killings of unarmed Black men and women by police and by lynch mobs took place between 1945 and 1951. They are displayed on the interactive map and detailed one by one in a descriptive list.
