As the 2024 presidential election approaches, the contrasting predictions of two prominent election forecasters, Allan Lichtman and Nate Silver, have captured attention. Lichtman, a professor known for correctly predicting nine of the last ten elections, foresees a win for Vice President Kamala Harris.
On the other hand, Nate Silver, founder of FiveThirtyEight, argues that the race is too close to call but personally leans toward a Trump victory.

Methods in Contrast
Lichtman and Silver have debated their respective methods publicly. Lichtman uses his “13 Keys to the White House,” a model developed with mathematician Vladimir Keilis-Borok, which evaluates the state of the country based on historical indicators. Each of the 13 keys is a true-or-false statement that, when six or more favor the opposition, predicts a win for the challenging party. For 2024, Lichtman asserts that eight of these keys favor Harris.
Silver, however, relies on probabilistic statistical models grounded in national and state polling data, economic indicators, voter turnout predictions, and other factors. His model adjusts for polling discrepancies and prioritizes reliable pollsters, aiming to provide a forecast based on shifting public sentiment.
Track Records
Lichtman has been successful in nine out of the last ten elections, only missing in 2000 when George W. Bush defeated Al Gore. Silver rose to prominence with his model accurately predicting 49 of 50 states in the 2008 election, and he correctly forecasted the 2012 and 2020 races. Notably, in 2016, Silver’s model gave Trump a 30% chance of winning, significantly higher than most other analysts at the time.
The Debate on Campaign Influence
Silver has questioned Lichtman’s reliance on historical data alone, suggesting it overlooks the influence of campaign events and shifts in public opinion. Lichtman, however, defends his model’s focus on fundamentals rather than campaign dynamics, arguing that the stability of historical patterns is what makes his approach successful. He claims that this approach mirrors how American presidential elections operate by focusing on enduring factors rather than the short-lived aspects of campaign cycles.
In contrast, Silver’s approach incorporates campaign developments and changes in voter sentiment, which he believes provide a more accurate picture of an election’s current state. According to elections analyst David Wasserman, Silver’s methodology is rigorous and more adaptable to polling variances and future events, recognizing the unpredictable nature of campaigns.
Challenges and Uncertainties
While Lichtman emphasizes the objectivity of his historical-based model, others criticize its disregard for economic perceptions, such as inflation concerns. Miller, a data science expert from Northwestern, notes that while the economy might look strong on paper, public sentiment regarding inflation could play a critical role in the election outcome. He also highlights flaws in Silver’s reliance on polling, as polls can underrepresent certain voter demographics or fail to accurately predict voter turnout.
Looking Ahead
Both Lichtman and Silver offer distinct insights into the presidential election landscape. Lichtman’s model leans heavily on patterns from past elections, suggesting that history often repeats itself in predictable ways. Silver’s model, however, examines the evolving sentiments of the American electorate, providing a flexible perspective that can adjust to contemporary shifts and trends.
As Election Day nears, the clash between these forecasting methods continues to spark debate about the accuracy of historical patterns versus the fluidity of public opinion in determining presidential outcomes.
