Hillary Clinton leads Donald Trump by 3 percentage points in Iowa, according to a survey of registered voters conducted this month by the Democratic firm Public Policy Polling.

Clinton, the presumptive Democratic presidential nominee, is the top choice for 44 percent of poll respondents, while 41 percent say they would vote for Trump, the presumptive Republican nominee.

The poll additionally shows that both candidates are underwater when it comes to favorability.

Almost two-thirds of Iowa voters — 64 percent — have an unfavorable view of Trump, while 33 percent view him favorably. Fifty-five percent of respondents have an unfavorable view of Clinton, compared with 42 percent who view her favorably.

Polling on the general election presidential race has been sparse in Iowa: No data has been released publicly since early January, when a PPP poll found Clinton and Trump tied and an NBC/Wall Street Journal/Marist poll showed Clinton leading by 8 points.

The PPP poll also tested the U.S. Senate race between six-term incumbent Republican Chuck Grassley and Democratic challenger Patty Judge.

Grassley is leading, with 48 percent of respondents saying they would vote for him, against 41 percent for Judge.

Forty-nine percent of voters have a favorable view of Grassley and 42 percent have an unfavorable view. Similarly, 48 percent say they approve of the job he’s doing as a U.S. senator, while 41 percent disapprove.

Judge, meanwhile, is positively viewed by 34 percent of respondents. Thirty-two percent have an unfavorable view and 34 percent are not sure.

The PPP poll was in the field June 9 and 10 and using automated telephone calls to survey 630 Iowa registered voters selected through a list based sample. The margin of error is +/-3.9 percent.

It was conducted on behalf of the Constitutional Responsibility Project, a group pressing for confirmation hearings for U.S. Supreme Court nominee Merrick Garland. Grassley, as chairman of the Senate Judiciary Committee, has refused to hold hearings and said the court appointment should be delayed until a new president takes office.
