Trump won just 14% of the vote in the 2016 Utah Republican caucus. Trump also did worse among Utah Republicans in the general election -- winning just 64% of them -- than he did among Republicans in any other state. Even after his anti-Trump rhetoric during the 2016 campaign, Romney won 71% of the vote in a primary against Republican Mike Kennedy in 2018. In other words, Romney scored 27 points higher with Utah Republicans in 2018 than Trump did with them in 2016. Put another way, Republicans in Arizona and nationwide were much more eager to have Republican members of Congress back Trump than Republicans in Utah were.
