This is the second poll this week that has shown a bump for Sen. Kamala Harris. | Joe Raedle/Getty Images 2020 elections National poll: Kamala Harris just 2 points behind Biden The California senator's polling surge continues, but Joe Biden still leads nationally and in Iowa.

Kamala Harris' polling surge continued Tuesday, as a pair of new polls — one of Iowa caucus-goers and another national poll — shows her leaping to second place.

The Iowa poll, conducted by USA Today and Suffolk University, showed Biden at 24 percent to 16 percent for Harris. Elizabeth Warren is in third at 13 percent, followed by Sen. Bernie Sanders’ 9 percent. Pete Buttigieg is at 6 percent, and Sens. Amy Klobuchar and Cory Booker are each at 2 percent, the last candidates above that mark.


A Quinnipiac University national poll has Harris right on Biden's tail. The former vice president has 22 percent and the California senator has 20 percent.

Warren follows Harris with 14 percent, with Sanders right behind at 13 percent. Buttigieg is at 4 percent and Booker is at 3 percent, the last candidate above 2 percent.

This is the second and third polls this week that have shown a big bump for Harris. A national CNN/SRSS poll released Monday also had Harris in second place, bunched with Warren and Sanders — and trailing only Biden.

This is the first poll that Suffolk University/USA Today has released in Iowa this cycle.

However, in a CBS News/YouGov poll in the state taken before the debates, Harris was in the middle of the pack.

This newly-released USA Today/Suffolk poll is a qualifying poll for the primary debates, according to the Democratic National Committee. With two weeks to go until the July 16 deadline to meet the DNC's criteria for the second debate, later this month in Detroit, the number of qualified candidates remains at 21 — the same 20 who debated last week, plus Montana Gov. Steve Bullock. But the DNC says it will use tiebreaker procedures to keep the field at 20 candidates.

For the third debate in September, candidates much reach 2 percent in four polls released between June 28 and August 28, in addition to receiving donations from 130,000 Americans.

Several candidates now have three qualifying polls for the September debate: Biden, Booker, Harris, Warren, Sanders and Buttigieg. Klobuchar has two qualifying polls.

Polls released by USA Today/Suffolk will use the results rounded to the nearest whole number, according to a memo sent to the campaigns by the DNC and obtained by POLITICO.

Suffolk initially reported some of its results out to two decimal places and rounded others. Most pollsters round their results to the nearest whole percentage point, as did USA Today, the DNC-approved media sponsor for this survey.

The Suffolk University/USA Today poll surveyed 500 likely Iowa Democratic caucus-goers from June 28-July 1. It has a margin of error of plus or minus 4.4 percentage points. The Quinnipiac poll surveyed 554 Democrats and voters leaning Democratic nationwide. It was in the field from June 28-July 1 and has a margin of error of plus or minus 5 percentage points.
