Donald Trump has widened the gap between himself and Democratic presidential hopeful Hillary Clinton, according to a new Utah Policy survey released Monday.

The Republican presidential nominee leads Clinton 39 percent to 24 percent in a five-way race that includes Libertarian nominee Gary Johnson, independent candidate and Utah native Evan McMullin and Green Party nominee Jill Stein.

Trump previously led his Democratic opponent by 12 percentage points in August. He continues to trail Clinton among independent voters, this time by 4 percentage points — 29 percent to 25 percent.

Despite growing up in Utah and headquartering his campaign there, McMullin has failed to gain much traction. It appears most of his support has come from previously undecided voters or individuals who supported other candidates besides Trump before McMullin entered the race.

However, while 82 percent of self-identified Democrats backed Clinton in the poll, far fewer Republican respondents (61 percent) said they plan to cast their ballot for Trump in November. Eleven percent of Republicans said they are considering Johnson, while 13 percent said they are open to voting for McMullin.

The survey of 605 likely voters in Utah was conducted Sept. 1-9. Results contain a margin of error plus or minus 3.98 percentage points.
