Millions of Americans headed to the polls in a pivotal election, casting their votes between Democratic nominee Vice President Kamala Harris and former President Donald Trump.

With polls showing a tight race, especially in key battleground states, the nation awaits a decision that could shape its future for years to come.

Both candidates took to Pennsylvania on Monday, holding simultaneous rallies in the Pittsburgh area, each projecting confidence in their campaigns. “Tomorrow is Election Day, and the momentum is on our side,” Harris told a crowd gathered at a historic steel facility, emphasizing her campaign’s vision for a new generation of leadership. “We know it is time for a change, and we will win.”

Trump, rallying at a packed sports arena, painted a starkly different picture. He promised a robust economic revival under his leadership, declaring, “If you vote for Kamala, you’ll have four more years of disaster. Vote for me, and America will experience unprecedented growth and opportunity.”

Early voting numbers reflect a significant turnout, with over 81 million Americans casting their ballots prior to Election Day—more than half of the total votes in the 2020 election when President Joe Biden defeated Trump. However, Trump has consistently questioned the integrity of the electoral process, insisting he would only accept the results if he deems them fair.

The stakes are monumental. A Trump victory would mark him as the second president in U.S. history to serve non-consecutive terms, while Harris would become the first woman, as well as the first person of South Asian descent and only the second Black president, following Barack Obama.

As both candidates campaign hard in these battleground states, polls show each has a shot at winning critical electoral votes, with Pennsylvania boasting 19 vital votes. According to various polling aggregators, the race is exceedingly tight and could swing either way. Historical trends suggest that the national popular vote does not solely determine the victor; rather, it’s the Electoral College that seals the outcome.

Harris has claimed the role of the underdog but has grown increasingly optimistic in recent days. Meanwhile, Trump has ramped up his rhetoric, framing the election as a battle against what he calls the “enemy within.” With both candidates relying on extensive legal teams to address any voting concerns, the path to victory remains murky.
