NEW YORK—Donald Trump scored a landslide victory in Indiana’s Republican presidential primary Tuesday, dealing a knockout blow to Texas Sen. Ted Cruz, who abruptly ended his campaign, making the real estate mogul turned insurgent candidate the party’s likely nominee this November. Just one other Republican remained in the race: Ohio Gov. John Kasich, whose advisers said he would continue to campaign. “It’s been an unbelievable day and evening and year,” Trump told reporters at an election night event at Trump Tower.
