In arm-wrestling terms, a new poll shows that GOP Rep. Mia Love and Democratic Salt Lake County Mayor Ben McAdams are grunting and pulling with all their might — but remain in a so-far-unmovable deadlock that tilts slightly in Love’s favor.

Similar to margins in many surveys over the past eight months, the pair is still 6 percentage points apart in a new Salt Lake Tribune-Hinckley Institute of Politics poll — which has a margin of error of 5 points, plus or minus. It is essentially a statistical tie.

“Of the major races in the state, this continues to be the one that is the closest,” said Jason Perry, director of the Hinckley Institute of Politics at the University of Utah. And it is not moving in either direction yet.

Love’s own pollster, Scott Riding with Y2 Analytics, said, “We have not seen movement” in her own surveys for months. “This confirms it.”

He adds that isn’t too surprising. “Voters are pretty busy now,” focusing on summer vacations and a just-completed primary election in other races. “Usually, undecided voters in the race start to tune in about Labor Day.”

In such a close race and poll, both sides see reasons to take heart. McAdams’ campaign cheers that he has a 2-1 margin of support among unaffiliated voters, a key group for him to win. Love’s camp enjoys her lead and says late-deciding voters in the district lean Republican, and she has a history of winning them.

The new poll shows Love leads McAdams 45 percent to 39, with 8 percent favoring others (even though no one else is on the ballot) and 8 percent undecided.

Data show that both candidates are holding their base well. McAdams is favored by 91 percent of Democrats, and Love is favored by 75 percent of Republicans.

“The effort right now is to win over independent voters because so many people in the Republican and Democratic parties have already made their decision,” Perry said. And 38 percent of all Utah voters are unaffiliated.

McAdams is doing better with that group — which actually outnumbers Democrats.

He is winning unaffiliated voters by a 53-27 percent margin.

“The mayor has done a really good job of reaching across party lines to get things done. That resonates well with unaffiliated voters, and that’s why he leads by a 2-1 margin with that group,” said Andrew Roberts, campaign manager for McAdams.

“The mayor has rolled up his sleeves and worked with the Republican speaker of the House as well as the Republican lieutenant governor to address our homelessness and opioid crises. And he has worked with the Republican County Council to do just about everything,” perhaps helping with GOP voters, too.

Riding isn’t worried. “There is a group of very thoughtful late deciders in the 4th District that always requires incumbents to prove that they deserve its vote. As the years have gone on, Representative Love has gotten more and more of them.”

The new poll also included a separate question asking voters if they approve or disapprove of Love’s performance in office.

It showed a plurality of voters approved by a 48 percent to 40 percent margin, with 11 percent undecided.

Among unaffiliated voters, a plurality disapproved by a 49-35 margin. Democrats also disapproved by an 83-11 margin. But Republicans approved 72-19.

“Fewer than half the voters in the 4th District approve of the job she’s doing. That’s a big problem for her,” Roberts said.

Perry, with the Hinckley Institute, said the favorability numbers reflect “year after year of very difficult and very contentious campaigns. Every campaign has been difficult and most of the time they have been fairly negative. I think those factors weigh on any candidate over a period of time.”

This year’s midterm elections are when the party of the incumbent president usually loses seats in Congress — and President Donald Trump has only mediocre approval in Utah and worse ratings in the 4th District, where 53 percent disapprove. His policies on immigration have been the target of much criticism by Utahns.

Riding says Love is positioned well to handle that, including recently speaking out against separating families of illegal immigrants at the border and supporting “Dreamers” brought as children by undocumented immigrant parents. She is a daughter of Haitian immigrants.

Love, a Utah Republican and the only Haitian-American in Congress, called on President Donald Trump to apologize after reports said he questioned why the United States was allowing immigrants from “s---hole countries” like Haiti, El Salvador and African nations.

“She’s eager to work with the president when that benefits her constituents,” he said. “There are places where she also disagrees, and has stepped up and tried to make her views known.”

But Roberts contends that Love is in lockstep with Trump. “She has supported the president 96 percent of the time. The mayor’s position is that nobody is right 96 percent of the time, and when he goes to D.C. he plans to work with people from both parties to do what’s right for Utah.”
