GOP frontrunner Donald Trump blasted the Republican Party leaders and Hillary Clinton during his campaign rally before roughly 5,000 supporters in Rome, New York, on Tuesday afternoon, where he also compared himself to President Ronald Reagan.

“He was behind Jimmy Carter by so much. Everybody said this is going to be a disaster. The last person Hillary wants to run against is me. But Jimmy Carter wanted to run against Ronald Reagan. By the time the election took place, it was an easy victory for Reagan,” Trump said, alluding to the fact that he can defeat Democratic frontrunner Hillary Clinton like Reagan defeated Carter.

“These are dirty tricksters,” Trump said about GOP officials and primary rules. “The Republican National Committee should be ashamed of themselves for allowing this kind of crap to happen … it has nothing to do with democracy.”

“The economy is rigged. The banking system is rigged. There’s a lot of things that are rigged in this world of ours,” the real estate mogul said. “We’re going to change it fast.”

“The party is playing dirty,” he charged. “They can’t get away with the stuff any longer.”

He said the Republican Party has had enough of the Mitt Romney types, calling them “stiffs that can’t get elected.”

“In Florida, it was set so I wouldn’t get it,” Trump said about the winner-take-all delegate rule in Florida, suggesting the Republican Party had that rule in place to benefit either former Florida Gov. Jeb Bush or Sen. Marco Rubio (R-FL) with all 99 Florida delegates.

“I want to be nice … only Marco,” Trump added, refraining from calling Rubio by his coined nickname “Little Marco.”

“Marco is actually a really nice guy,” Trump added, just a day after an interview published in whivh he said he would consider Rubio as his vice president.

“I want to be nice,” Trump stated. “I want to be presidential.”

Trump made a notable mistake during his speech when he was referencing his endorsements and meant to mention Jerry Falwell Jr. of Liberty University but instead referenced “Bob Vander Plaats from Liberty University.”

Bob Vander Plaats is CEO of The Family Leader and endorsed Sen. Ted Cruz (R-TX).
