In a significant departure from nearly three decades of practice, the Teamsters union has announced that it will not endorse any presidential candidates for the upcoming election. This decision comes despite internal polling indicating a substantial portion of its members support Donald Trump. Amid tensions, various local Teamsters unions in key swing states such as Michigan, Pennsylvania, and California have chosen to endorse Kamala Harris and Tim Walz, diverging from the national union's stance. As the situation evolves, some officials express frustration over the national leadership's decision, while others are concerned about the implications of the union's lack of endorsement for both major party candidates. Democratic leaders and activists have reacted strongly, viewing this non-endorsement as a setback for their campaign. The Teamsters' leadership has faced criticism for their handling of endorsements, with some members claiming a disconnect between the national leaders and grassroots sentiments.
