Five years ago this week, Donald Trump’s presidential campaign hit a snag. The second Republican primary debate had not gone well, and he was taking so much flak for failing to correct an Islamophobic supporter at a rally in New Hampshire that he canceled an event in South Carolina scheduled for the next day. In just 72 hours, he seemed to go from dominant front-runner to an amateur making rookie mistakes. Heading to Iowa on September 19 for a meeting of the Faith and Freedom Coalition, where every major Republican candidate was making an appearance, he apparently decided to try something new.
