A poll released by Montana State University Billings gives incumbent U.S. Sen. Jon Tester a 9-point lead over his challenger.
Tester, a Democrat, received 47 percent support from poll participants. Matt Rosendale, the Republican running to unseat Tester, took in 38 percent. The margin of error was 4.5 percent.
Jason Adkins, political science assistant professor and director of the poll, said that within the candidates' respective parties, Tester had more support. There were more undecided voters among Republicans for this race.
But the undecided vote might lean to the right, according to the poll. Adkins said that 58 percent of those undecided voters in this race support President Donald Trump.
"We think a good majority of those might vote for Matt Rosendale in the end," he said.
Libertarian candidate Rick Breckenridge polled at 3 percent, while 12 percent remained undecided in the Senate race.
Twelve MSUB students in a media, public opinion and polling class conducted the poll with Adkins leading the way. They surveyed a random statewide group of 471 likely voters via telephone Oct. 8 through Oct. 13.
Among those polled, 32 percent identified as Republican and 26 percent identified as Democrat. Independents made up 38 percent.
The university has conducted these polls since 1989, and this year saw the 31st installment. Adkins released the results Tuesday, just two weeks before Election Day.
The MSUB poll shows a wider lead for Tester than a recent poll from Montana State University and the Montana Television Network. That poll put Tester just 3.1 points ahead of Rosendale. Though in both polls, Tester's lead falls within the margin of error.
The MSUB poll showed a narrower gap in the U.S. House race. Republican Congressman Greg Gianforte took 44 percent over Democrat Kathleen Williams' 41 percent. The difference between them is within the margin of error.

The poll also asked respondents about their confidence in law enforcement. Sixty-seven percent said they had a great deal or quite a lot of confidence in law enforcement. Adkins said that there was a party split, as fewer Democrats than Republicans expressed a great deal of support, which was the highest mark in the poll.
Finally, Montana voters are in line with national surveys about federal lawmakers. Some 65 percent disapproved of Congress in the MSUB poll.
"Only 15 percent of voters approve of Congress in this state," Adkins said.
