Democrat Kamala Harris leads Republican Donald Trump 45% to 41% in a Reuters/Ipsos poll published Thursday that showed the vice president sparking new enthusiasm among voters and shaking up the race ahead of the Nov. 5 election.

The 4 percentage point advantage among registered voters was wider than a 1 point lead Harris held over the former president in a late July Reuters/Ipsos poll. The new poll, which was conducted in the eight days ended Wednesday and had a 2 percentage point margin of error, showed Harris picking up support among women and Hispanics.

Harris led Trump by 49% to 36% — or 13 percentage points — among both women voters and Hispanic voters. Across four Reuters/Ipsos polls conducted in July, Harris had a 9 point lead among women and a 6 point lead among Hispanics.
