I recall that one of the issues in the 1960 election was that the Mayor Daly political machine in Chicago delivered  dead voters' votes for JFK.  

The story at the time was that when Nixon suggested a challenge that he was dissuaded when his political team pointed out that the Republicans in the southern part of Illinois had been 'voting the graveyard' as well and an honest recount would have to be across the entire State.  

No challenge was made in any event.
