A bit more than a dog whistle at this point:

In most years, what Rudy Giuliani said on today’s Sunday morning talk shows could be dismissed as a conspiracy theory with no greater consequence or relevance. But this isn’t most years.

“Dead people generally vote for Democrats instead of Republicans,” Giuliani said on CNN’s State of the Union with Jake Tapper, insinuating that American cities are hotbeds of widespread voter fraud. “If you want me to tell you that I think the elections of Philadelphia and Chicago are going to be fair, I would have to be a moron to say that.”

This is flatly wrong. Despite Giuliani’s dystopian fever dreams, election experts are clear that voter fraud is extraordinary rare, had no impact on the 2012 race, and isn’t expected to be a problem in 2016. As Tapper correctly pointed out, even the Republican Party of Philadelphia agreed that there was no voter fraud in the city.
