Gov. Gary Herbert is now enjoying sky-high approval ratings â but the only groups of Utahns who applaud the Legislatureâs performance highly are Republicans and âvery activeâ Mormons. A new poll by The Salt Lake Tribune and the Hinckley Institute of Politics shows that Herbertâs performance is strongly or somewhat approved by 71 percent of Utahns, while 26 percent somewhat or strongly disapprove, with 3 percent undecided. That is up significantly from 15 months ago.
