In South Florida, a challenge is emerging for two-term Democratic Congressman Jared Moskowitz. Oliver Larkin, a union organizer, is running against him from the left. Larkin's campaign is focused on portraying Moskowitz as too moderate.

This local race is part of a larger trend seen in recent weeks. Incumbents in other states have lost primaries to candidates identifying as Democratic Socialists. Further details on this developing story are available from CBS4 Miami, including an interview with Oliver Larkin.
