According to a handful of new public opinion polls, Harris is leading anywhere between 2 percentage points and 5 percentage points, although many were within the margin of error. This marks a shift from polls at the beginning of the week when the two candidates were essentially tied.

A Reuters/Ipsos poll, the first to be conducted since the debate, had Harris ahead by 5 points, 47% to 42%, a 1-point rise from a poll recorded in the week after the Democratic National Convention last month. There was a 3% margin of error. The poll showed that 53% who watched the debate believed Harris came out on top, as opposed to 24% thinking Trump did.

A Morning Consult survey of 3,317 likely voters conducted on Sept. 11, the day after the debate, put Harris ahead of Trump 50% to 45%, with a margin of error of 2 percentage points. The poll also found a majority of respondents believed Harris won the debate.

A Yahoo/YouGov poll conducted a couple of days later showed Harris leading Trump 50% to 45%, with a margin of error of 2.9%. The results were an improvement for Harris from a previous Yahoo/YouGov poll, in which Harris led Trump 47% to 46% in the week after the Democratic National Convention from Aug. 22 to Aug. 26.

A Leger poll of 1,174 likely voters, conducted between Sept. 10 and Sept. 11 for the New York Post, showed Harris leading Trump 47% to 44%, with a margin of error of 2.72 percentage points.

While national surveys give important views of the electorate, the state-by-state results of the Electoral College will determine the winner.

Trump was leading in a new poll in North Carolina, a critical battleground state, in the aftermath of the debate. Trump led Harris 48.4% to 46% among likely voters, according to a Trafalgar Group poll released on Saturday. The poll was conducted on Sept. 11 and Sept. 12.
