Donald Trump supercharged his hostile takeover of the Republican Party on Super Tuesday, scoring big wins in at least six states as he threatened to break away from his GOP rivals in the delegate chase.

Ted Cruz kept hold of his home state of Texas and won neighboring Oklahoma. And Marco Rubio was almost shut out on a brutal night, only picking up Minnesota.

But the story of the day — again — was Trump, as the Manhattan mogul continued to steamroll, winning states as diverse and distant as Alabama and Massachusetts.

He's now won in the South. He's won in the West. He's won in the Northeast.

"This has been an amazing evening," Trump declared during a Tuesday evening press conference at his Mar-A-Lago estate in Florida, as New Jersey Gov. Chris Christie stood by his side.

Trump dismissed his GOP rivals, undercutting Cruz's Texas win ("I know how hard he worked, actually.") and calling Rubio a "little senator" who "had a tough night."

Instead, Trump looked ahead to a contest with Hillary Clinton.

"Making America great again will be better than making America whole again," he said, mocking the slogan she pushed in her own victory speech on Tuesday night.

Vermont was still too close to call on the evening of the biggest delegate haul of the 2016 nominating contest. There, John Kasich was in second, not far behind Trump. A total of 595 delegates — nearly half those needed to secure the nomination — were up for grabs across a dozen states.

It was not a good night for Rubio, who was flirting with failing to meet the 20 percent threshold to win delegates in several key states in early returns, including Alabama, Tennessee, Texas and Vermont.
