Donald Trump has slammed the U.S. election system. The presidential candidate described the arrangement as "all rigged."

The Christian Science Monitor reported that the real estate magnate has continued to blast Republican insiders. On Friday, the Republican presidential aspirant shared his thoughts on the U.S. election system at a Delaware rally.

"The system is all rigged," Trump said. "That's why we have to win big. That's why on Tuesday, everyone has to go out and vote. We have to win big because the system is rigged."

The publication noted that the real estate magnate's "foot-stomping" has become his rally's cry to increase turnout and strengthen his appeal to voters. His argument is described as a "convenient scapegoat."

"The fighters have a great expression," Trump stated on Friday. "When you have a champ that goes into a big territory but it's unfriendly; it's home of the other fighter."

"But the good ones go, 'No, no, I'm not worried.' Because if I knock him out there's nothing the judges can do. Right? What we have to do is knock them out with the volume of our votes."

Trump's campaign aide Paul Manafort clarified that the presidential candidate is only criticizing the U.S. election system. Apparently, the system is "rigged in all 50 states" and "don't take into account modern presidential campaigns."

"That's where things are getting confused," Manafort said. "He's saying we've got to change rules so the next time, when people vote, their vote counts."

According to Business Insider, Donald Trump scorned candidates who fight each other ruthlessly for six months but shower the ultimate victor with praises in the end. He added that Americans will not be hearing anything like that from him.

"The one who loses says, 'I just want to congratulate my opponent," Trump said in a rally on Sunday in Maryland. "He is a brilliant man, he'll be a great governor or president or whatever.'"

"I'm not sure you're ever going to see me there. I don't think I'm going to lose, but if I do, I don't think you're ever going to see me again, folks."
