Presidential front-runner Donald TrumpDonald John TrumpDems flip Wisconsin state Senate seat Sessions: 'We should be like Canada' in how we take in immigrants GOP rep: 'Sheet metal and garbage' everywhere in Haiti MORE in a Super Tuesday victory speech presented himself as a unifying figure who is expanding the Republican Party by turning out long-dormant votes.

Speaking from Palm Beach, Fla., flanked by New Jersey Gov. Chris Christie, Trump made the case that he’s growing the Republican Party, even as a big faction of the establishment is plotting to stop his march to the nomination.

“I’m a unifier,” Trump said. “Once we get all of this finished, I’m going after one person and that’s Hillary ClintonHillary Diane Rodham ClintonIntel Dem decries White House 'gag order' after Bannon testimony 'Total free-for-all' as Bannon clashes with Intel members Mellman: On Political Authenticity (Part 2) MORE, on the assumption she’s allowed to run.”

The real estate mogul pointed to record-setting turnout in the Republican primaries that has dwarfed Democratic turnout, and said it’s because he’s attracting Democrats and Independents who have never before participated.

“Our party is expanding and all you have to do is take a look at the primary states where I’ve won,” Trump said. “We’ve gone from one number to a much larger number. That hasn’t happened to the Republican Party in many, many decades. So I think we’re going to be more inclusive, more unified and a much bigger party and I think we’re going to win in November.”

Trump had claimed victories in Virginia, Georgia, Alabama, Massachusetts and Tennessee by 10 p.m. and could win as many as nine of the 11 states that will award delegates on Super Tuesday.

Still, many Republicans are panicked over the possibility of Trump winning the nomination.

The New York Times reported on Tuesday that big group of influential donors will direct resources to a super-PAC with the sole purpose of stopping the billionaire’s march to the nomination.

But Trump said he was not worried in the slightest by the establishment’s efforts to stop him.

“They can always do that and they’ll just lose everything and that would just be the work of a loser,” Trump said. “I will say this. Look, we’ve expanded the Republican Party.”

Speaking from Florida, Trump put Marco RubioMarco Antonio RubioOvernight Cybersecurity: Bipartisan bill aims to deter election interference | Russian hackers target Senate | House Intel panel subpoenas Bannon | DHS giving 'active defense' cyber tools to private sector Senators unveil bipartisan push to deter future election interference Puerto Rico's children need recovery funds MORE on notice that he plans to win the senator’s home state and take the 99 delegates in the winner-take-all contest on March 15.

Rubio has had a tough Super Tuesday; he’s yet to win a state.

“We’re going to Florida and we’re going to spend so much time in Florida,” Trump said.

“We’ve got about a 20-point lead. I know that a lot of groups and special interests and lobbyists who want to have their little senator do exactly as they want, they’re going to put $20 or $25 million into it over the next two weeks and frankly that’s fine. If he wins they’ll have total control, but he’s not going anywhere anyway.”
