Republicans Secure White House and Congress in 2024, Raising Questions About Future Dynamics

Donald Trump wins presidency with narrow margin as GOP gains control of both chambers, but structural challenges and voter patterns suggest uncertainties ahead.

Donald Trump defeated Kamala Harris in the 2024 presidential election by a 1.6-point margin, the fifth-smallest in a century, while voter turnout dropped compared to 2020.
Republicans gained control of the Senate, flipping four seats, and retained their House majority, achieving a governing trifecta alongside the presidency.
Despite the GOP's victories, Trump’s coattails were limited, with significant drop-offs in down-ballot support for Republican Senate candidates in key states like Michigan and Nevada.
Democrats performed better than expected in swing states, flipping House seats in New York and California and retaining competitive Senate seats in Trump-won states like Nevada and Wisconsin.
Looking ahead, Republicans face structural advantages in the 2026 Senate map, but uncertainties remain about their ability to sustain power without Trump on future ballots.
