US President Barack Obama has called for a thumping victory of Democratic nominee Hillary Clinton against Donald Trump to repudiate the Republican presidential nominee’s "dangerous" claims of a rigged vote.

Speaking on Thursday evening at a rally in support of Clinton in Miami, Florida,  Obama called on supporters of Clinton, “We’ve got to do it big; there has to be no doubt. Because the Donald is whining that the one is going to be rigged before the game is even over.”

Trump has challenged the legitimacy of American democracy, saying that he might not accept the results of the November 8 presidential election if there is evidence it was rigged.

During the final presidential debate with Clinton on Wednesday night, Trump indicated he could launch a legal challenge if his rival won through rigging tactics.

Obama accused Trump of “doing the work of our adversaries for them” by refusing to commit to accepting the election results.

"There is no way to rig an election in a country this big," he said. "You are much likelier to get struck by lightning than have somebody next to you commit voter fraud."

Speaking in Delaware, Ohio, on Thursday, Trump said only if he wins the election he will accept the results. “I will totally accept the results of this great and historic presidential election — if I win.”

Obama accused Trump of trying “to sow the seeds of doubt in people's minds about the legitimacy of our election” and undermining “our democracy”.

"When you suggest rigging or fraud without a shred of evidence, when last night at the debate, Trump becomes the first major party nominee in American history to suggest that he will not concede despite losing... that is not a joking matter,” he stated.

Obama reiterated his earlier assertions that Trump is unfit to serve as commander in chief of the armed forces.

American political analyst and activist Myles Hoenig told Press TV hours before the final debate that Trump has no proof that the Democratic Party or Clinton are stealing the election from him, but “rigging elections is all-American.”

Hoenig said the establishments of both Democratic and Republican Parties are trying to silence Trump because they fear that the talk of rigging “would create chaos and mistrust of the final results.”
