Again, it doesn’t matter. Even if you assume Romney won half of the states that he won in 2012, if neither he nor Trump won any Obama states, Hillary would walk away with a majority of the delegates, end of story. So in order for this to work, you have to somehow assume that Trump or Romney will take several states from Hillary splitting the GOP vote that Romney was not able to win alone. There’s just no way that could happen.
Again, who would win Utah?
