As the United States stands on the brink of what many are calling the most consequential presidential election in recent history, the nation is focused on the battleground state of Pennsylvania, where both Vice President Kamala Harris and former President Donald Trump organised last-day rallies. RFI's Jan van der Made looks back at a campaign marked by unprecedented polarisation.
The bitter rivals embarked on a final frenzied campaign blitz Monday with both hitting must-win Pennsylvania on the last day of a tight and volatile US presidential election campaign.
Pennsylvania is the single biggest swing state prize under the US Electoral College system, which awards influence in line with population.
Republican Trump has promised a "landslide" as he seeks his return to the White House, while Democrat Harris said the "momentum" was on the side of her bid to be America's first woman president.
Deadlock
But the polls suggest a different story on the eve of Election Day – total deadlock in surveys nationally and in the seven swing states where the result is expected to be decided.
The world is anxiously watching the election, which is set to have profound implications for conflicts in the Middle East and Russia's war in Ukraine, and for tackling climate change.
Both sides say they are encouraged by early turnout numbers, with over 78 million people having voted already, around half of the total number of ballots cast in 2020.
No middle ground
The closeness of the 2024 White House race reflects a deeply divided United States, as it chooses between two candidates whose visions could scarcely be more different.
Media outlets and political parties have poured millions of dollars into advertising campaigns that leave little room for middle ground.
This stark divide is a reflection of the American political system, where the winner-takes-all approach often marginalises third-party candidates and reinforces the dominance of the two major parties.
US elections: Who are the running mates for the key candidates?
As election day approaches, the spotlight has fallen on undecided voters who may ultimately tip the scales in this tight race.
Campaign volunteers have been working tirelessly, engaging directly with potential voters in an effort to sway opinions and drive turnout.
To discuss what is at stake, RFI's Jan van der Made spoke to analyst J. Wesley Leckrone, Chair Political Science Widener University, Daniel Hopkins, Political Scientist University of Pennsylvania and Daniel Laurison, Associate Professor Sociology at Swarthmore College and former campaigner for Barack Obama.
