Trump led a July edition of the same poll by 2 points.

The GOP presidential nominee has improved among independent voters, leading Clinton, his Democratic rival, 44 percent to 29 percent.

But both are still plagued by negative favorability ratings.

“Iowa is one of the few places where Trump has been able make inroads among voting blocs that generally support Clinton,” said Patrick Murray, director of the Monmouth University Polling Institute.

Trump has been gaining ground in the polls both nationally and in several battleground states. Clinton now leads Trump by less than 2 points nationally, according to a RealClearPolitics polling average.

Thursday’s poll comes one day after Monmouth University released a poll in Nevada that showed Trump overtaking Clinton by 2 points.

Grassley has 56 percent, with Judge at 39 percent.

Grassley has expanded his lead since July, when he led Judge by 10 points. His favorability rating has also improved, with 50 percent saying they view the GOP senator favorably, while 29 percent view him unfavorably. Judge has a positive favorability rating as well, but she’s relatively unknown; 52 percent have no opinion.

The poll was conducted from Sept. 12 to 14 and surveyed 404 likely voters in Iowa via phone. The margin of error was 4.9 percentage points.
