In the ABC/Ipsos poll, Harris leads Trump 52%-46% among likely voters, and 50%-46% among all adults and registered voters - a slight lead among all voters but a full lead among likely voters, ABC reported.
Harris also holds leads in all but one of the seven swing states: Michigan (+2.4%), Wisconsin (+3.2%), Pennsylvania (+1.2%), Nevada (+0.7%), Georgia (+0.5%), Arizona (+0.3%). Trump leads in North Carolina (+0.3%), but even that advantage has been evaporating steadily.
On a Labor Day when Harris and vice presidential nominee Tim Walz campaigned in several states and Trump was inactive, voters have been more impressed with the Democrats' campaign.
"Notably, 93% of Democrats and 56% of independents rate Harris' campaign positively, as do 24% of Republicans in this poll, produced for ABC by Langer Research Associates with fieldwork by Ipsos," ABC reported. "Fewer across groups see Trump's campaign positively - 79% of Republicans, 38% of independents and 13% of Democrats."
If the polling is correct, Harris might surge even more next week: By a 6-point margin, 43%-37%, the public picks Harris to win the ABC News presidential debate on Sept. 10 - 86% of Democrats expect her to win the debate, while 79% of Republicans expect Trump to win it. Independents pick Harris by 7 points.
