The results come as Trump and Harris have focused their attention almost exclusively on seven battleground states that are expected to shape the outcome of the election. Neither has campaigned in Iowa since the presidential primaries ended, and neither campaign has established a ground presence in the state.
A victory for Harris would be a surprising development after Iowa has swung aggressively to the right in recent elections, delivering Trump solid victories in 2016 and 2020.
The poll shows that women — particularly those who are older or who are politically independent — are driving the late shift toward Harris.
