On November 5, American voters will head to the polls to choose their next president. Originally, this election was expected to be a rematch of the 2020 race between President Joe Biden and former President Donald Trump. However, the race took an unexpected turn in July when Biden ended his campaign and endorsed his Vice President, Kamala Harris. This shift has raised a major question: will the U.S. see its first woman president, or will Donald Trump return for a second term?
As election day approaches, we’ll track the latest polls and analyze how each candidate’s campaign is impacting the race.
National Polls: Who is Ahead?
Since Harris entered the race in late July, she has maintained a narrow lead over Trump in national polling averages, though the gap has fluctuated over the past months. Initially, Harris enjoyed a significant boost, reaching a nearly four-point lead by the end of August. Her numbers stabilized throughout September, even following the only debate between her and Trump on September 10, a widely viewed event that attracted almost 70 million viewers. However, recent polling indicates a tightening race as the gap between them has narrowed.
National polls, though indicative of a candidate’s popularity, don’t guarantee an election outcome. The U.S. presidential election operates through an electoral college system. Each state is allocated a certain number of electoral votes proportional to its population, totaling 538 votes. A candidate must secure at least 270 to win the presidency. Consequently, the true battleground lies not in national support but in key swing states where both candidates have a viable chance of winning.
Battleground States: Who Leads Where?
In the crucial swing states, the contest remains extremely close. Polling averages show no clear frontrunner in these decisive states, which include Arizona, Georgia, North Carolina, Nevada, Michigan, Pennsylvania, and Wisconsin.
Since Harris entered the race, the data has shown interesting trends in these states, though the limited number of state-level polls and their inherent margin of error complicate any definitive conclusions. In Arizona, Georgia, and North Carolina, for instance, both candidates have traded the lead since early August, with Trump pulling slightly ahead in recent weeks. In Nevada, Harris has held a slight edge.
In Michigan, Pennsylvania, and Wisconsin, Harris consistently led by two to three points since early August. However, polling in these states has also tightened significantly. Notably, Trump has taken a small lead in Pennsylvania, a state critical for both candidates due to its relatively high number of electoral votes among the swing states. A win in Pennsylvania could greatly improve either candidate’s path to the 270 electoral votes needed for victory.
These three states were Democratic strongholds until Trump flipped them red in 2016, helping him secure the presidency. In 2020, Biden reclaimed them for the Democrats. Should Harris manage to hold these states, her path to the White House would be significantly easier. Her campaign’s gains underscore the changes since Biden left the race. On the day he withdrew, he trailed Trump by almost five points across the swing states and by 4.5 points in Pennsylvania alone. This trend shift highlights the importance of these battleground states and Harris’s appeal in those areas Biden struggled to secure.
How Polling Averages Are Created
The polling data in the graphics presented above are averages calculated by the polling analysis site 538, part of ABC News. To determine these averages, 538 gathers results from individual polls conducted by various polling firms across the nation and in swing states. Only polls from companies meeting specific quality standards—such as transparency about sample size, polling dates, and data collection methods—are included in these averages.
These standards ensure reliability to a certain extent, but all polls come with inherent limitations, which 538 addresses by applying a consistent methodology to create an average that ideally reflects overall trends.
Can the Polls Be Trusted?
Polls currently show Harris and Trump nearly tied across most swing states, suggesting an extremely close race. Given the small margins between them, it’s challenging to predict a winner based solely on current data.
Historically, polls have underestimated Trump’s support, as seen in the 2016 and 2020 elections. Polling companies have since adjusted their methods to better capture voter sentiment. They are now trying various approaches to make poll results more representative of the voting population’s composition. However, these adjustments are complex, requiring educated assumptions about voter turnout and other unpredictable factors that can only be tested once voters actually cast their ballots on November 5.
