The International Brotherhood of Teamsters has announced it will not endorse any presidential candidate for the 2024 election, marking a significant departure from its recent tradition of supporting Democrats. This decision follows internal polling revealing that nearly 60% of its members favor Donald Trump over Kamala Harris, raising concerns about the union's political alignment amid divisions among its membership. Teamsters President Sean O’Brien cited a lack of serious commitments from both candidates on key union issues as a primary reason for the non-endorsement. The Teamsters' choice contrasts with other major labor unions that have rallied behind Harris, highlighting a shift in the political landscape among union workers. Despite the strong preference for Trump within the membership, the union emphasized the importance of representing all members, regardless of political affiliation. This marks the first time in almost 30 years that the Teamsters have chosen not to endorse a candidate, reflecting changing sentiments among labor organizations.
