In 1983, the Socialist Workers Party (SWP) expelled two groups: First, the Fourth Internationalist Tendency (FIT). Second, the group that would coalesce around the Socialist Action (SAct) newspaper. SAct argued that they were expelled for defending Trotskyist ideas of Permanent Revolution, class independence, and continued support for the Fourth International.[5] The first issue of its newspaper contained no listing of an editorial board.[6]
In 1992, during the Gulf War, SAct was active in the San Francisco Bay Area antiwar movement through the National Campaign Against the War in the Middle East, which competed with the Workers World Party-led Coalition Against a Vietnam War in the Middle East.[10]
In 2019, a minority faction was expelled or resigned membership from Socialist Action and re-established as Socialist Resurgence.[11]
The party has claimed that the Euromaidan revolution in Ukraine was a "US-backed fascist coup", alongside claiming that Ukraine banned the Russian language.[12]
In 2020, SAct again nominated Mackler.[14] SAct again gained no ballot access or write-in status in any state.
In 2016, SAct nominated their first presidential ticket, selecting national secretary Jeff Mackler for president and Karen Schraufnagel for vice-president.[16] However, SAct got no ballot access or write-in status in any state, and thus received zero votes.
In 2018, SA member and Iraq War veteran[18] Fred Linck hoped to run as Socialist Action candidate for United States Senate in Connecticut. The party submitted over 11,000 signatures to the Connecticut Secretary of State, but too many were disqualified for Linck to be placed on the November ballot. Linck asserted that local officials incorrectly invalidated signatures.[25] Despite being left off the ballot, Linck continued to run for office as an official write-in candidate, and ultimately received 70 votes, or 0.01%.[19]
