Public polls give a general sense of where an election might be headed for. However, they are not necessarily a true indicator of the final election results. We track the averages from the national polls conducted across the United States of America for the key candidates during the last three Presidential elections to show how the public perception and support for the candidates swayed through the campaigns: Donald Trump vs Hillary Clinton (2016), Donald Trump vs Joe Biden (2020) to Donald Trump vs Kamala Harris (2024). Fresh daily data will be added to this live updating poll tracker until November 5, 2024 - the election day.
