Romney announced earlier this month he won't seek a second term, saying younger people needed to step forward. In so doing, he threw open a wider door for those seeking to enter the race and led to speculation about whether Utah voters will choose a politically moderate successor similar to him or a farther-right figure such as Utah's other U.S. senator, Mike Lee, a Trump supporter.
