Is Utah the most anti-Trump red state?

Also, Utah would have looked a lot different if McMullin never ran. Trump would have done better there.

Or much of what would've been McMullin's support could've gone to Gary Johnson (before McMullin, remember that he was polling pretty high and he should've targeted that state to get some influence).

The only reason why Trump's victory in Utah was so narrow was because of McMullin's independent run. If McMullin didn't run, Trump would've won it by 60-70% like other Republican nominees.

Probably not the case; prior to McMullin entering the race, polling in Utah showed Gary Johnson with >20% of the vote. Trump might've done a couple points better, but it's difficult to see him eclipsing 50, and virtually impossible to see him eclipsing 55. Keep in mind that Trump was saved a little bit by how unpopular Bill Clinton was in Utah (he came in third here in 1992); polls during the primary season showed Sanders could conceivably have broken 40 here, and probably competed against Trump.

Exactly.
