Pennsylvania voters demonstrated remarkable enthusiasm as polls opened on Tuesday in a state vital to this election's outcome. Social media videos displayed long lines of voters waiting even before the 7 a.m. opening.

One video showed 80 to 100 individuals in line outside a Jenkins Township polling station in Luzerne County. Similarly, the University of Pennsylvania saw voters lining its halls ahead of the official poll opening time. In York County, eager voters were reported to have gathered as early as 5:55 a.m., more than an hour before the polls opened. Turnout was notably high in Erie County too, with around 100 voters seen queuing by 7 a.m.

This election holds immense significance as Pennsylvania, carrying 19 Electoral College votes, has a history of siding with the winning candidate in 48 of the past 59 elections. Polls remain extremely tight, with statistical aggregator FiveThirtyEight showing Kamala Harris a mere 0.2 points ahead, whereas Nate Silver's tracker presented Donald Trump with a slim 0.1 point lead.

Individual polls paint a similarly close picture. AtlasIntel's recent survey, conducted from November 3 to 4, indicates Trump leading by one point. In contrast, Survation's poll, taken between November 1 and 4, places Harris two points ahead, while Research Co.'s poll from November 2-3 shows just a one-point advantage for Harris. Additionally, an Echelon Insights poll from late October reported Trump ahead by five points in a multicandidate race—potentially the largest Republican margin since Ronald Reagan's seven-point win in 1984.

Jon Parker, a senior lecturer in American studies at Keele University in the U.K., highlighted the significance of voter commitment on election day, attributing the outcome to high turnout.

Early voting data indicates a higher turnout among Democrats, who represent 56 percent of early voters compared to 33 percent for Republicans. Gender dynamics also play a critical role, with 54 percent of early voters being women, potentially driven by Harris' focus on reproductive rights.

According to the latest John Zogby Strategies poll, 27 percent of voters identified abortion as their primary election issue, with the same percentage of female voters highlighting its importance in Survation’s Pennsylvania poll. This emphasis on reproductive rights may be critical in determining the election's outcome in this tightly contested state.
