Historians point out the differences between the two close elections.
And there was another key difference in 1960. It had been a hard fought campaign with almost eerie similarities to this one. Allegations of fraud were lobbed by both sides. Nixon later said with the volatile situation in the world, a Cold War in process, an ongoing crisis in Cuba, he didn't feel he could risk a drawn-out challenge. Richard Nixon had the grace, even though he knew there were irregularities in Illinois in the 1960 presidential election and that he had probably won the election, he had the good grace not to challenge the election results and not disrupt our Constitution.
