Kamala Harris leads Donald Trump in Michigan by 11 percentage points and by two points in Arizona, Wisconsin and Nevada, according to the Bloomberg News/Morning Consult online poll conducted from July 24-28. Trump has a four-point advantage in Pennsylvania and a two-point lead in North Carolina, while the pair are tied in Georgia. Wisconsin is the only state among the seven where the former President has narrowed the gap with Harris.

The poll results were released the same day that Harris launched a 50 million USD advertising campaign, with a one-minute spot titled "Fearless." It was her first big ad buy since consolidating support for the Democratic nomination after President Joe Biden dropped out of the race on July 21 and endorsed her.
