DES MOINES — The polls seem to agree on Chuck Grassley’s lead in his re-election bid.

A new Quinnipiac University poll published Thursday shows Grassley, Iowa’s longtime Republican U.S. Senator, with a lead of 9 percentage points over Democratic challenger Patty Judge.

In a survey of 846 likely Iowa voters conducted Aug. 8 through Tuesday, 51 percent said they plan to vote for Grassley and 42 percent said they plan to vote for Judge. The margin of error was 3.4 percentage points.

That lead is consistent with what other polls have shown on the Senate race in Iowa.

In five of the six most recent polls tracked by Real Clear Politics, Grassley’s leads over Judge were between 7 and 10 percentage points.

The lone outlier is a Loras College poll from late June that showed Grassley leading by just 1 percentage point.

“Iowans have known, liked and voted for Sen. Chuck Grassley for decades. That’s why he appears in [a] strong position to avoid the kind of down-ballot bloodletting that may hurt some Republicans in other states who are not as well attuned to the views and values of their home base,” Peter A. Brown, assistant director of the Quinnipiac University Poll, said in a news release.

Brown said Grassley is faring better than some other Republican candidates because Donald Trump, the Republican candidate for president, is faring better in Iowa than other states.

In Quinnipiac poll results published Wednesday, Trump trailed Democrat Hillary Clinton by just 3 percentage points. That is much closer than in some other election battleground states; for example, Clinton leads Trump by double digits in Colorado and Virginia, according to recent Quinnipiac polls there.

“Sen. Grassley’s chances for re-election also are helped by the fact that Donald Trump is running better in Iowa against Hillary Clinton than Trump is in many other states,” Brown said.

In Quinnipiac’s poll on Iowa, Grassley and Judge both have strong support from within their respective parties, but Grassley leads by 20 percentage points among no-party voters, 57 percent to 37 percent.
