If Utah’s lone Democrat in Congress, Rep. Jim Matheson, gets in the Senate race, voters would be evenly split, according to the poll, with 47 percent favoring Hatch and 47 percent for Matheson.

Hatch’s most likely GOP challenger appears to be Rep. Jason Chaffetz, R-Utah. In a primary race, 40 percent of poll respondents said they would vote for Hatch and 41 percent for Chaffetz.

Among a slightly smaller sample of voters who said they were likely to vote in a Republican primary, Hatch was ahead of Chaffetz, 47 percent to 44 percent.

But should Chaffetz win the GOP nomination, he wouldn’t fare much better against Matheson in the general election. The poll showed 46 percent would vote for Chaffetz and 45 percent for Matheson.
