I think that is attributable to how Mormons are perceived in the West. Contrary to the vitriol displayed by Mormon defenders here, The West recognizes Mormons as staunch patriots with Conservative and Christian principles.
I really believe the Mormon tag along with Romney's stated positions caused people to accept him at face value rather than digging into his record. I dare say that most had no idea he was from the Northeast, not to mention that he was a liberal governor in very liberal Massachusetts.
Even so, the greater dichotomy is rather stunning. Huck won the South, and the lower Midwest, while Romney won the Mountain West and the upper Midwest. An interesting difference that I would like to see explained.
Maybe Southerners have long memories of a bad history.
We are daily told [by the Mormons]
that we, (the Gentiles,) of this county are to cut off, and our lands appropriated by them for inheritance. Whether this is to be accomplished by the hand of the destroying angel, the judgments of God, or the arm of power, they are not fully agreed among themselves.

If gentiles (Missourian Old Settlers) did not wish to live among the Mormons, they would be forced to sell out to them and most likely at a loss
. On the other hand, if the gentiles attempted to remain in Jackson County, Mormon immigration ensured the Saints would soon make up the majority of the population, which would thereby permit them to oust the old settlers through ostensibly legal methods.
