The biggest changes, according to the Fox polling, come from the independent and Hispanic voters.
In August, independent voters favored Trump by 8 points. They now favor Harris by 12 points.
Last month, Hispanic voters favored Trump by 6 points. They are now favoring Harris' campaign by 12 points.
"It is important to remember that estimates among small subgroups are more volatile and tend to swing more than others, and that applies here," Fox noted.
In August, Fox also shared that Harris was closing the gap with Trump in the Sun Belt states, which includes Florida, Alabama, Mississippi, and Texas as well as battleground states like Georgia, South Carolina, Arizona and Nevada.
Harris also holds onto many of Biden's voters from the 2020 election, with 93 percent of his voters, according to Fox. Trump also, however, is keeping nearly all of his voters from four years ago, at 94 percent. Among 2020 non-voters, Harris is up by 3 points.
"Harris' advantage over Trump on a variety of personal traits is clearly helping her," says Shaw. "It's a big deal that she's been able to fight to a draw on protecting free speech despite aggressive
Republican efforts to highlight the Biden administration's censorship of right-leaning views on social media."
