As the 2025 US presidential election draws closer, a crucial question arises: who will secure the White House, Kamala Harris or Donald Trump? After President Joe Biden ended his campaign and endorsed Vice President Kamala Harris in July, the race took a new direction. This shift has made the election a rematch of the 2020 battle, but with Harris as the Democratic nominee and Trump aiming for a second term. Polls have been closely monitored to gauge public sentiment, showing fluctuating trends as both candidates vie for key battleground states.
US Election Polls 2025
National polls suggest that Harris has maintained a slight lead over Trump, although this margin has narrowed in recent weeks. However, national polls alone do not predict the winner, as the US electoral system operates on an Electoral College basis. This system places more importance on swing states, where both candidates are focusing their efforts. With the stakes high and swing states too close to call, the outcome of this election remains uncertain, and polling data continues to evolve.
