Quick note: The new Bloomberg/Morning Consult poll shows Harris improving the chances of victory in 6 of 7 swing states:
The poll - conducted online from July 24-28 - shows Harris leading Trump in Michigan by 11 percentage points, while in Arizona, Wisconsin and Nevada, she has a 2-point advantage. Trump is ahead of Harris in Pennsylvania by 4 points and in North Carolina by 2 points. They are on equal footing in Georgia.
Wisconsin is the only state of the seven where Trump has narrowed his deficit with Harris in comparison to Biden's performance in a previous poll.
Harris gaining ground on Trump in 6 of 7 swing states, Bloomberg poll shows
If you have a subscription to Bloomberg, you can read a more detailed analysis. The part I found most intriguing was the level of enthusiasm, and increased interest in voting:
The switch-up in candidates looks set to boost the turnout in swing states, where there’s evidence that key constituencies for the party have been energized by her candidacy. More than one-third of voters in the seven battlegrounds said they’re much more likely to vote now that the contest is between Trump and Harris, and the numbers rose to 49% and 44% among Black and Hispanic voters respectively.
