Significance The recent improvement in Democratic prospects raises the chance of Republican-led challenges to results in battleground states should Trump lose. A Democratic preponderance of officeholders in these states means fraud claims are unlikely to succeed but they should be expected. Impacts Latest polls show Kamala Harris closing the gap with Trump to 1-2 percentage points (pp) in key states where Biden was 6 pp behind in July. Republican legislatures are keeping concern about election integrity alive this year by passing bills presented as a means to prevent fraud. Claims that non-citizens are illegally voting in state and federal elections remain unsubstantiated and unlikely.
