Trump vs. Harris · September 25, 2024
Harris’ Post-Debate Bump Dissipates
ActiVote’s September 25, 2024 presidential poll finds that Vice President Harris has a lead of 2.8% on former President Trump. The poll was in the field between September 18 and September 24 (median field date of September 21). The poll was among 1000 likely presidential election voters and has an average expected error of 3.1%.
Trump leads among rural voters, while Harris leads among suburban and urban voters. Harris leads among younger voters (18-49) and the elderly (65+) while Trump leads among those 50-64. Harris leads among women, while Trump leads among men. Both get about 85% of those affiliated (30 states) or estimated to be affiliated (20 states) with their party, while Harris has a narrow lead among independents. Trump leads among White voters, while Harris gets 71% of the Black vote and a majority of Latino voters. There are only small differences between income and education categories.
Please note that the percentage of Black voters supporting Harris in this poll is significantly lower than in two previous ActiVote polls (76% and 88% in other September polls). If the population-wide actual support is closer to 80%, then all these results could be just natural statistical variation (the MoE on this item is just over 8%).
Also note that typically BSC+ voters are found to lean Democratic. Recent support percentages in ActiVote polls were 59%, 55% and 58%. It suggests that the 49% support in this poll may be an outlier.

Daily Tracking Poll
ActiVote runs (internally) a daily poll consisting of the last 1000 user responses to determine the state of the race. As soon as such a daily poll no longer overlaps in field period with our previous published poll, we publish that poll with all relevant details. The race trend graph shows the daily movement in the top-line result of our tracking poll, starting July 27th. It is only provided as an illustration of possible momentum in the race and overall movement over time based on ActiVote polling.
The trend suggests that Harris’ poll numbers improved steadily for about 3-4 weeks after Biden dropped out, followed by a period of 2 weeks where it hovered around a 5-point lead, which came down to a 2-3% lead around Labor day, and stayed there for a while, before starting a steady climb post the September 10 debate, and now, two weeks after the debate some of the post-debate gain seems to have dissipated.
