I do not believe any poll out of Utah. Ritt Momsey and his Mormon Tabernacle choir control just about every major polling institution.
In reality Utah is tired of Mormon invective , and there is a substantial revolt against the Mormon influence in politics, which is why Utah’s Lt. Governor endorsed Donald Trump.
So do not count The Donald out yet in Utah. I am sure there will be some very serious fights in the Utah caucuses, and it likely will be a very late night before the returns are all in.
