The 2024 U.S. presidential election seemed to have the potential to profoundly impact the national economy, financial markets, and geopolitics. Did Donald Trump’s re-election influence Americans’ psychology as well? We conducted a 7-wave longitudinal survey tracking N = 623 Americans (36% male, M age = 45.05 years ( SD age = 22.97) from 3 weeks before the election to 16 weeks after. As the election results came in, Democratic supporters reported a decrease in well-being, optimism and personal control, lower institutional trust, higher cynicism, more experiences of disrespect, and a stronger conspiracy mentality—changes that persisted up to 4 months post-election. In contrast, Republican supporters experienced changes in the opposite direction, effectively reversing the previously observed liberal advantage in institutional trust and diminishing the liberal–conservative gap in other psychological outcomes. These results challenge the notion of inherent psychological differences between liberals and conservatives, highlighting how such differences can shift depending on which party holds power.
