Former President Donald J. Trump capped off a clean sweep of Republican delegates in Michigan on Saturday during a raucous convention, which further exposed a deep fissure in the state party that threatens to fester in one of the most important battleground states. Mr. Trump, the Republican front-runner, amassed at least 90 percent of the vote in all but one of the state’s 13 congressional districts against former Gov. Nikki Haley of South Carolina, who was ambassador to the United Nations under Mr. Trump. A simple majority was needed in each district to win its share of delegates at the caucus-style event, giving Mr. Trump 39, to go along with the 12 that he won in Michigan’s primary, which was held on Tuesday. Ms. Haley emerged from that contest with four delegates.
