The International Brotherhood of Teamsters has decided not to endorse any candidate for the upcoming presidential election, marking the first time in nearly three decades that the union has refrained from making an endorsement. This decision follows internal polling indicating that approximately 58% of members support Donald Trump over Kamala Harris, who is the Democratic nominee. Teamsters President Sean O'Brien expressed disappointment over the lack of serious commitments from both candidates on critical union issues. The union's non-endorsement puts it at odds with other major labor organizations that have backed Harris. Grassroots groups within the Teamsters are mobilizing to support Harris, highlighting divisions within the union's membership. The Teamsters' choice reflects a changing political landscape among union workers, traditionally a key demographic for Democrats.
