Polls show Vice President Kamala Harris leading former President Donald Trump since becoming the Democratic presidential nominee, a reversal from Trump’s lead over President Joe Biden—as Harris reaches the Democratic National Convention with an edge of three points or more, according to several new surveys.

Key Facts

Harris had a three-point advantage over Trump (46%-43%) in an Economist/YouGov poll of registered voters taken Aug. 17-20 and released Wednesday, with Robert F. Kennedy Jr. at 3% and other candidates earning a negligible share—roughly similar to Harris’s 46%-44% lead about a week earlier.

Harris led Trump 48% to 44% in a Morning Consult poll of registered voters released Tuesday, up from a two-point edge by the same pollster last week, as Morning Consult shows independents picking Harris over Trump 42% to 38% as the vice president’s approval rating ticks up to 50% (the poll’s margin of error was 1 point, and voters were surveyed from Aug. 16 to 18).

Harris is leading Trump 49% to 45% among registered voters and 51% to 45% among likely voters, a poll by Ipsos, ABC News and The Washington Post said Sunday.

In a CBS and YouGov poll, also released Sunday, Harris has a three-point edge over Trump among likely voters (51% to 48%) leading into the Democratic National Convention this week, though the candidates are tied at 50% in battleground states.

Harris leads 50% to 46% in an Emerson College poll of 1,000 likely voters released Aug. 15.

Just one major poll in the last week, taken by Fox News and released Aug. 15, found Trump leading, 50% to 49% among registered voters.

Some 48% of registered voters polled by Monmouth University in a survey released Aug. 14 said they will definitely or probably vote for Harris in November, compared to 43% who said they would definitely or probably vote for Trump.

Harris leads in several other surveys taken this month: a Reuters/Ipsos poll released Aug. 8 found Harris leads 42% to 37%, and an NPR/PBS News/Marist poll released last Aug. 6 shows her polling 48% to 45% over Trump.

Trump leads Harris in at least eight other polls since President Joe Biden dropped out of the race, but most show Harris denting Trump’s lead over Biden and her approval rating ticking up since she announced her candidacy.

Trump led Harris by one point (48% to 47%) in a New York Times/Siena poll conducted July 22-24, two points (49% to 47%) in a July 23-25 Wall Street Journal poll and by two points (47% to 45%) in a HarrisX/Forbes online survey released June 26.

Big Number

1.5. That’s how many points Harris leads Trump by in RealClearPolitics’ latest polling average. Meanwhile, FiveThirtyEight’s weighted average shows Harris with a 2.9-point lead.

Surprising Fact

The Monmouth University poll found Democratic enthusiasm has nearly doubled since Harris’ entrance into the race, from 46% in June to 85% now, while enthusiasm among Republicans has stayed stagnant at 71%.

How Does Harris Perform Against Trump In Swing States?

Harris leads Trump by one point overall in the seven battleground states likely to decide the election: Michigan, Pennsylvania, Wisconsin, Nevada, Arizona, North Carolina and Georgia, according to a Cook Political Report survey released Wednesday. Harris leads Trump in five of the seven states, is tied with him in Georgia and is trailing Trump by three points in Nevada, the Cook poll found.

Contra

Trump campaign pollster Tony Fabrizio predicted a “short term” bump in polls for Harris in the coming weeks as her entrance into the race is expected to reenergize Democrats, referring to the anticipated boost as a “Harris Honeymoon” in a memo released shortly after the Reuters/Ipsos poll was made public.

Key Background

Biden dropped out of the race on July 21 after resisting calls from within his own party for weeks to end his reelection bid in the wake of his disastrous performance in the June 27 debate. Biden immediately endorsed Harris and she announced plans to seek the nomination. The party has quickly coalesced around her, with 99% of Democratic delegates voting to officially nominate her in a virtual roll call that concluded last week. The following day, Harris announced Minnesota Gov. Tim Walz as her running mate, weeks after Trump announced Ohio Sen. JD Vance as his pick for vice president at the start of the Republican National Convention on July 18. Democrats hold their convention next week, Aug. 19-22, in Chicago.
