Romney could be a thorn in Trump's side

Orrin Hatch has been a US Senator since 1977 but the 83-year-old may announce that he will step down before next year's midterms.

If so, former GOP Presidential candidate Mitt Romney plans to run for his seat, according to a report from utahpolicy.com.

Romney is a classic establishment Republican and is not on good terms with the President. In any case, the seat is almost-certain to remain Republican. It's just a matter of which flavor of Republican it will be.
