Donald Trump and Hillary Clinton scored huge victories Tuesday that bring them closer to a monumental duel for the White House in the fall.<br />Trump's political strength was on display with a clean sweep of races in Maryland, Delaware, Pennsylvania, Connecticut and Rhode Island.<br />Clinton delivered big wins in Maryland and Pennsylvania -- the biggest prizes of the night -- along with Delaware and Connecticut.<br />Bernie Sanders picked up his sole victory of the night in Rhode Island.<br />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 and avoid a contested Republican convention.<br />That historic prospect is now the only way rivals Texas Sen. Ted Cruz and Ohio Gov. John Kasich could stop Trump from becoming the GOP nominee.
