Again, this is debatable whether you weigh the damage done by 4 years of Trump to the Republican party. Especially if he fails to get a PV majority and loses Utah to cost him the presidency. There would be lots of pressure on republicans to nominate Clinton outright if she wins the PV.
In short, chaos. This won't happen though, as Clinton will romp if McMullin wins. However, it would be the finishing blow to a decrepit campaign.
Also the GOP does. not. want. indies winning EVs and showing up on the map. It makes sense for the GOP to spend money to obliterate McMullin. Especially if they believe that Trump has already lost.
