Vice President Kamala Harris holds a narrow two-percentage-point lead nationally over Republican Donald Trump, after Joe Biden’s resignation and the announcement of her candidacy, according to a Reuters/Ipsos poll.

The poll, conducted on Monday and Tuesday, comes after Republican National Convention where Trump formally accepted his party’s nomination on Thursday and after Biden announced on Sunday that he was dropping out of the race and endorsing Harris.

Harris, whose staff said she has secured the delegates to support her candidacy, leads Trump by 44% to 42% in the national polla difference however within the margin of error of 3 percentage points.

Harris and Trump both drew 44% in a July 15-16 poll, with the former president leading by one percentage point in a July 1-2 poll. Both findings, however, are within statistical error.

While national surveys provide important findings regarding support for political candidates, only a few states prove decisive based on the Electoral College in who wins the presidential election.

The latest poll also reflects how voters judge Biden’s decision to leave, but also the announcement of Harris’ candidacy.

About 56% of registered voters responded positively to whether they considered Harris, 59, “mentally sharp and up to the challenge.” compared to 49% who said the same about Trump, 78. Only 22% of voters rated Biden favorably on this question.

About 80% of Democratic voters said they view Biden favorably, compared to 91% who said the same for Harris. Three-quarters of Democratic voters said they agree the party and voters should get behind Harris now, with only a quarter saying there should be multiple candidates.

In the hypothetical scenario involving a ballot with independent presidential candidate Robert F. Kennedy Jr., Harris led Trump by 42% versus 38%, percentage outside statistical error. Kennedy, who polls 8% of voters, has yet to win the support of many state delegates ahead of the Nov. 5 election.

Many respondents to the Reuters/Ipsos poll said they did not know the Democrats considered as possible candidates.
About one in four registered voters said they had never heard of U.S. Transportation Secretary Pete Buttigieg, a former Democratic presidential candidate who garnered the most support, 37 percent, as the challenger to Harris.

One in three said they didn’t know about California Governor Gavin Newsom, with about the same percentage saying they viewed him favorably. Half of registered voters in the poll had never heard of Arizona Sen. Mark Kelly, and two-thirds knew nothing of Kentucky Gov. Andy Beshear.

The poll, which was conducted online, polled 1,241 US adults nationwide, including 1,018 registered voters.
