Interesting question is Utah with the commission which the legislature can ignore but what if the governor feels the need to have good government and refuses a gerrymander with some moderates in the legislature?
Hmmm... Huntsman in particular seems unlikely to sign a commission override bill if he is the next governor, but it may not matter. Republicans have nearly 80% of the seats in both chambers (and only 1 seat flipped in each last year), so they can lose a lot of votes and still do a veto override.
The optics of repealing the commission outright would be really, really bad. I don't think that is what will happen. It's more likely that they edit the commission's criteria/procedure in a way that would lead to a more Republican-leaning map. For example, removing the COI criterion, or removing the municipality (SLC) splitting provision but keeping the minimal county splits one.
What would the partisan numbers be on a SLC district that only included the most Republican parts of the county?
Something like R+10 (DRA doesn't have Presidential 2016 numbers)
The DRA version I use has 2016 presidential numbers

Utah does not have 2016 data yet. Only 2008.
