Story highlights Rudy Giuliani backed up Donald Trump's claim that the election could be rigged

Giuliani said fraudulent votes could make a difference in narrow races

Washington (CNN) Top Donald Trump adviser Rudy Giuliani claimed Sunday that Democrats could steal a close election by having dead people vote in inner cities, while vice presidential candidate Mike Pence said the ticket will "absolutely accept the result of the election."

"I'm sorry, dead people generally vote for Democrats rather than Republicans," the former New York City mayor told CNN's Jake Tapper on "State of the Union." "You want me to (say) that I think the election in Philadelphia and Chicago is going to be fair? I would have to be a moron to say that."

But he did say the amount of cheating would only impact extremely close races -- noting, for example, if either Trump or Hillary Clinton won Pennsylvania by "5 points," the cheating he alleges would occur would be negligible and not change the outcome.

Giuliani was backing up Trump, the Republican nominee, who has repeatedly claimed on the campaign trail -- without providing evidence -- that his race against Clinton is being rigged.

Trump tweeted Sunday: "The election is absolutely being rigged by the dishonest and distorted media pushing Crooked Hillary - but also at many polling places - SAD"
