Utah is a bit weird when it comes to Trump due to the high value placed on pretending in public to be morally upright. Romney plays that part perfectly. However, Utah is a very conservative state, so that will mostly keep Romney in line. He also doesn’t suffer from the McCain syndrome of massive ego paired with limited intelligence and anger control issues.
I’m thinking that Romney will be a one-term senator. He won’t be able to help himself when the opportunity to be a globalist, liberal, whiny RINO bitch presents itself - which will be often. Without the 17th Amendment, the Utah legislature would just recall his ass and replace him...
