Utah hasn't gone Democratic in 52 years, but Donald Trump may be turning it into a swing state. His campaign against Islam reminds Mormons of brutal persecution against their religion. Doubling down on his appeal to the base, he's asking evangelical Christians not just to vote for him, but to pray for him, too. That's troubling other constituencies, including white women who favor women's rights and same-sex marriage. In the process, Trump is accentuating divisions within the Republican Party that are likely to outlive his presidential campaign.
