The Close US Presidential Election: What Will Decide the Outcome

The outcome of the current US presidential election is experiencing an unprecedented level of uncertainty in recent political history, presenting a high-stakes contest. While past elections have been decided by narrow margins—for example, George W Bush’s 2000 victory over Al Gore hinged on a few hundred votes in Florida—there has usually been some indication of the race’s trajectory in its final days. This perception has occasionally been inaccurate, as demonstrated in 2016 when polls overestimated Hillary Clinton’s strength and failed to detect a late shift in Donald Trump’s favor. This time, however, all signs are pointing in various directions, making it impossible for anyone to credibly forecast the winner. The majority of final polls fall well within the margin of error, both at the national level and within the seven crucial battleground states that are poised to decide the election. Based purely on statistical data and sample sizes, this indicates that either candidate could currently hold a lead. This pervasive uncertainty is a source of frustration for political pundits and campaign strategists alike. A few surprises have emerged, including a recent respected survey in Republican-leaning Iowa that indicated a surprising lead for Harris. However, the major polling averages and the forecasting models that interpret them uniformly characterize this contest as a coin-toss. The current uncertainty regarding the election’s outcome does not imply that the final result will not be decisive; a shift of merely a few percentage points in either direction could allow a candidate to secure all battleground states. If voter turnout models are incorrect, and a greater number of women, rural residents, or disaffected young voters participate, the final results could undergo a dramatic change. Surprises might also emerge among key demographic groups. It remains to be seen whether Trump will truly achieve the predicted inroads with young black and Latino men, as his campaign has suggested. Similarly, it is unclear if Harris is successfully attracting a larger proportion of traditionally Republican suburban women, as her team hopes. Another question is whether elderly voters—who reliably participate in every election and generally lean to the right—are now moving into the Democratic column. After this election has concluded, it may be possible to definitively identify the reasons for the winning candidate’s success. In hindsight, the explanation might become obvious. Nevertheless, anyone asserting knowledge of the immediate outcome is misleading both others and themselves. While the outcome of the presidential vote is largely predetermined in most US states, seven key battleground states will ultimately decide this election. However, not all battleground states hold equal significance. Each candidate has identified a “wall” of three states that represents the most direct path to the White House. Harris’s so-called “blue” wall, named for the Democratic Party’s color, extends across Pennsylvania, Michigan, and Wisconsin in the Great Lakes region. This area has been a significant focus of political discourse since 2016, when Trump narrowly won all three traditionally Democratic states on his path to victory. Joe Biden subsequently reclaimed these states in 2020. If Harris can retain them, she would not need any other battleground, assuming she also secures a congressional district in Nebraska (which utilizes a slightly different system for awarding its electoral college votes). This explains why she has dedicated the majority of her time to these blue wall states during the campaign’s final stretch, spending full days on the ground in each. On Monday night, she conducted her final rally in Philadelphia, Pennsylvania, at the summit of the 72 steps leading to the city’s Museum of Art, a location famously climbed by Sylvester Stallone’s fictional boxer Rocky in the film of the same name—before he narrowly lost to his opponent, Apollo Creed. Trump’s “red wall” is located along the eastern edge of the US. Although it receives less discussion, it is equally critical to his electoral chances. This wall commences in Pennsylvania and extends south to North Carolina and Georgia. If he secures these states, he will win by two electoral votes, regardless of the results in other battlegrounds. This explains his decision to hold five events in North Carolina within the last week. Pennsylvania, the largest battleground electoral prize, is the common point where both of these “walls” intersect. Its nickname, the Keystone State, has never been more appropriate. The historic significance of this presidential election is sometimes overshadowed by the extensive electoral map strategizing and political maneuvering. Harris and Trump represent fundamentally different visions for the US, particularly concerning immigration, trade, cultural issues, and foreign policy. The president elected for the next four years will have the capacity to shape American government, including the federal courts, in ways that could have generational impacts. The US political landscape has undergone dramatic changes over the past four years, reflecting shifts in the demographic compositions of both parties. The Republican Party of a decade ago presented a very different image compared to the populist one Trump now leads, which holds significantly more appeal for blue-collar and low-income voters. While the Democratic Party’s base continues to rely on young voters and people of color, it now increasingly draws support from the wealthy and college-educated. Tuesday’s results may offer further evidence of how these significant shifts in American politics, only partially realized over the past eight years, are reshaping the US political map. These changes could potentially grant one side or the other an advantage in future races. It was not long ago—in the 1970s and 1980s—that Republicans were widely considered to have an unassailable lock on the presidency because they consistently secured a majority in enough states to prevail in the electoral college. While this election may be a 50-50 contest, this does not necessarily signify a new normal in American presidential politics.
