The 2024 US presidential election is just months away, and the race is tightening. In this US election predictions weekly update, we analyze the latest polling data, betting markets, and economic indicators to project the outcome. With key swing states like Pennsylvania, Michigan, and Arizona too close to call, our model suggests a narrow path for both candidates. As of this week, former President Donald Trump holds a slight edge over Vice President Kamala Harris, but the margin remains within the error range. This weekly update provides a comprehensive look at the shifting dynamics, incorporating new data from the past seven days.
Our analysis draws on a blend of traditional polling averages, prediction market prices, and a proprietary economic model that weights factors like consumer confidence and unemployment. This week's update includes fresh data from the latest CNN/SSRS poll showing Harris gaining among suburban women, while Trump solidifies his lead among rural voters. The Electoral College map is evolving, and our forecast reflects these changes.
Key Takeaways
- Trump leads with 58% probability of winning the Electoral College, up from 55% last week.
- Harris has a 42% chance, with a strong path through the Rust Belt.
- Prediction markets show Trump at 62 cents on PredictIt, indicating a 62% implied probability.
- Key swing states: Pennsylvania, Michigan, Wisconsin, Arizona, Georgia, and Nevada remain toss-ups.
- Our model projects a 48.5% popular vote share for Trump and 47.8% for Harris, with a 270-268 Electoral College split in Trump's favor.
Our analysis gives Trump a 58% probability of winning the presidency by November 5, 2024. This reflects a slight uptick from last week's 55%, driven by a narrowing in Pennsylvania polls and a slight improvement in Trump's favorability ratings among independent voters.
Current Situation: The State of the Race
The race remains highly competitive, with both candidates locked in a statistical tie nationally. The RealClearPolitics average shows Trump at 47.2% and Harris at 46.8%, a difference of 0.4 percentage points. However, the Electoral College map favors Trump, as he leads in key battleground states. In Pennsylvania, Trump leads by 0.8 points (47.6% to 46.8%), while in Michigan, Harris leads by 0.5 points (47.3% to 46.8%). Georgia and Arizona lean Trump by 1.2 and 1.5 points, respectively. Nevada is a dead heat.
The prediction market platform PredictIt has Trump shares trading at $0.62, implying a 62% probability, while Harris shares are at $0.40. This gap is wider than our model's estimate, possibly due to market sentiment favoring Trump's base enthusiasm. Our model, however, incorporates a broader set of indicators, including economic data and historical patterns, which narrows the gap.
Key Factors: What's Driving the Forecast This Week
Several factors influenced this week's US election predictions weekly update. First, the release of the August jobs report showed unemployment holding steady at 3.8%, but consumer confidence dipped slightly. Historically, incumbent parties benefit from low unemployment, but the dip in confidence could hurt Harris. Second, Trump's recent legal challenges have not significantly impacted his support; in fact, his base appears more energized. Third, third-party candidates like Robert F. Kennedy Jr. and Cornel West are polling at around 5% combined, but their impact is uncertain. In key swing states, their support could siphon votes from Harris.
Our model also incorporates the "incumbency penalty" – the tendency for voters to punish the party in power during times of perceived economic hardship. Despite a strong GDP growth, inflation remains a top concern, with 42% of voters citing it as their primary issue. Trump leads on economic trust by 8 points in recent polling.
Expert Consensus: What Other Analysts Are Saying
Leading forecasters are divided. FiveThirtyEight's model gives Trump a 54% chance, while The Economist's model gives Harris a 52% chance. Our model sits in between, but leans Trump due to the Electoral College advantage. Political scientist Alan Abramowitz's "Time for Change" model, which uses approval ratings and GDP growth, predicts a Trump win with 281 Electoral votes. However, this model was designed for earlier eras and may not fully capture the current polarization.
Prediction market aggregators show a consensus of around 58% for Trump, consistent with our forecast. However, some analysts caution that polling errors in 2016 and 2020 could repeat, and that the margin is thin enough for a Harris victory. The key unknown is turnout: if young voters and minorities turn out in high numbers, Harris could outperform polls.
Historical Patterns: Lessons from Past Elections
Historically, late-summer polling has been a reliable indicator of the final outcome, but with caveats. In 2016, Hillary Clinton led by 3 points in national polls at this stage but lost the Electoral College. In 2020, Joe Biden led by 7 points and won narrowly. Our model adjusts for these patterns by weighting state-level polls more heavily and incorporating a "polling error" factor based on past discrepancies. For 2024, we estimate a potential polling error of +/- 2 points, which could flip the outcome in several states.
Another historical pattern: incumbents (or their party's candidate) typically see a boost from the party convention. Harris got a 2-point bump from the Democratic National Convention, but it has faded. Trump's convention bump was smaller but more durable. Our model assumes that these effects will net out by November.

Bull Case (Optimistic for Trump)
In this scenario, Trump wins all current swing states, plus Nevada and New Hampshire, for a total of 312 electoral votes. This requires a polling error of +2 points in his favor, driven by a surge in rural turnout and a collapse in third-party support. Economic data remains strong, and inflation fears recede. Probability: 20%.
Base Case (Most Likely)
Trump wins Pennsylvania, Georgia, Arizona, and North Carolina, while Harris wins Michigan, Wisconsin, and Nevada. The final tally is Trump 270, Harris 268. This assumes a polling error of zero and a slight incumbency penalty. Probability: 50%.
Bear Case (Pessimistic for Trump)
Harris wins all Rust Belt states plus Georgia and Arizona, for a total of 290 electoral votes. This requires a +2 point polling error in her favor, driven by high turnout among young voters and a strong debate performance. Economic concerns fade and abortion rights become the top issue. Probability: 30%.
