I saw a book by RFK, Jr., in a bookstore once and looked through it. He was convinced that George W. Bush had stolen the 2004 from Kerry by stealing Ohio's electoral votes. (Even though GWB had a 3 million vote margin over Kerry in the popular vote, if Kerry had taken Ohio he would have won...so much for the Democrats who want to abolish the electoral college.) The evidence? Apparently a couple of places in Ohio had long lines at the polling places...I don't think he offered any evidence that was the result of malfeasance by local Republican officials.
GWB's plurality in Ohio in 2004 was about the same as JFK's plurality in the entire country in 1960.

Chicago held out till last reporting When the DNC chair called mayor daley to ask what was happening, Daley reportedly said, how many votes do you need. Between Sam Giancana and the unions and the democrat city controlled by Daley, no way Kennedy would lose the election.
When told of irregularities, Nixon decided to not take action “for the good of the country.”
