I found this interesting:
The Communist Party USA, officially the Communist Party of the United States of America (CPUSA),[9] is a communist party in the United States which was established in 1919 after a split in the Socialist Party of America following the Russian Revolution.
…
By August 1919, only months after its founding, the Communist Party claimed to have 50,000 to 60,000 members. Its members also included anarchists and other radical leftists. At the time, the older and more moderate Socialist Party of America, suffering from criminal prosecutions for its antiwar stance during World War I, had declined to 40,000 members. The sections of the Communist Party’s International Workers Order (IWO) organized for communism around linguistic and ethnic lines, providing mutual aid and tailoring cultural activities to an IWO membership that peaked at 200,000 at its height.
I knew communism was rather popular in the 1920s. I just didn’t know how popular.
As of 2024 membership was about 15,000. But it is claimed:
Democrats’ defeat in November has actually caused defections of some left wing voters to alternative parties like Democratic Socialists of America (DSA) and Communist Party USA (CPUSA).
CPUSA membership has more than quadrupled in the past decade, growing from ~5,000 members in 2017 to probably 20,000 in early 2025.
And CPUSA reported a surge of membership applications after the ’24 elections due to left wing disillusionment with the failing Democrat Party.
Depending on your definition of a communist, CPUSA numbers don’t represent the true number of communists in this country. The Democrats have moved leftward enough to incorporate large numbers of them.
I have to wonder, percentage wise, are there more communists in the country now than in the 1920s?
