Real estate mogul Trump swept the GOP's five presidential primaries, extending his delegate lead over Sen. Ted Cruz of Texas and Ohio Gov. John Kasich. Former Secretary of State Clinton, meanwhile, won four of the five Democratic contests, adding to her advantage over Sen. Bernie Sanders of Vermont.
Those results made a Clinton-Trump general election contest more likely than ever, and both candidates acknowledged that their opponents' chances were dwindling. Those declarations came 86 days after the tumultuous primary-caucus season began in Iowa on Feb. 1.
"As far as I'm concerned, it's over," Trump said after his Tuesday night victories.
