Just a random idea I had. What would happen if the Mexican-American War was delayed by about 4-12 years, or didn't happen at all? Specifically, what would happen to the Mormons, who were in the process of moving to OTL Utah (then under Mexican control) when the OTL Mexican-American War happened? Would it even be safe to assume that they would still be in a position to move if the US was focused more on internal affairs than on expansionism?
