In a significant departure from tradition, the Teamsters union has opted not to endorse any presidential candidate for the upcoming election, aligning its decision with internal polling that shows a substantial member preference for Trump over Harris. Despite the national leadership's neutrality, several local chapters, including those in Iowa and Wisconsin, have publicly backed Kamala Harris, signaling a fracture within the organization. Teamsters President Sean O'Brien has faced criticism for this non-endorsement, with some viewing it as a failure of leadership, while others argue it sends a clear message to both major parties that their approaches are insufficient. This unprecedented move raises questions about the future influence of the Teamsters in electoral politics, especially given their historical support for Democratic candidates.
