Former President Donald Trump and Vice President Kamala Harris are locked in a tight race in the battleground state of Arizona.

A Noble Predictive Insights poll, released Tuesday, found Mr. Trump leading Ms. Harris 47%-44%, which is within the poll’s margin of error.

The same survey found in May that Mr. Trump held a 44% to 41% lead over President Biden, who abruptly pulled out of the race a month ago.

The latest findings showed that the number of undecided voters in the poll shrank to 9% from 15% in May and that Ms Harris pulled support from third-party contenders, including Robert F. Kennedy, who endorsed Mr. Trump this week.

“People are happier about the major party options now that Biden is gone,” said NPI CEO Mike Noble. “That’s why RFK Jr. saw such a dramatic drop in the polls — and likely, in part, why he left the race.”

Also in the poll, Mr. Trump was most trusted among voters on immigration, inflation and taxes, while Mr. Harris was more trusted on abortion, climate change and education.

The poll showed that Ms. Harris was running stronger than Mr. Biden was among independent, Hispanic and young voters. She leads Mr. Trump among those slices of the electorate.

Conducted from Aug. 12-16, the poll included 1,003 registered voters in Arizona and had a 3% margin of error.
