To my knowledge, this is the first poll showing us the wishes of Utah voters in this presidential primary season. It is the SurveyUSA Poll -- done between January 6th and 13th of a random sample of 989 registered Utah voters. The margin of error for Democrats is 7.2 points, and among Republicans is 4.9 points.
Clinton has a significant 10 point lead among Democrats over Sanders (50% to 40%), while the top four candidates among Republicans (Cruz, Trump, Carson, Rubio) are all within the margin of error of each other.
