Trump’s political strength was on display with a clean sweep of races in Maryland, Delaware, Pennsylvania, Connecticut and Rhode Island. Clinton delivered big wins in Maryland and Pennsylvania — the biggest prizes of the night — along with Delaware and Connecticut. Bernie Sanders picked up his sole victory of the night in Rhode Island.

The wins for Trump — following a massive victory last week in New York — move him significantly closer to the 1,237 delegates he needs to win the nomination outright heading into the convention in July. In the process, he inflicted serious blows on the legitimacy of claims by rivals Texas Sen. Ted Cruz and Ohio Gov. John Kasich that he should be deprived of the nomination.

“This to me was our biggest night,” Trump said in his victory speech. “I consider myself the presumptive nominee.”
