“Nixon had prevailed by just 140 votes, according to the initial results, which were certified by the governor. A recount was underway on Dec. 19, 1960, when presidential electors across the nation were required by law to meet and cast their ballots.”
“between John F. Kennedy and Richard Nixon, who was vice president at the time.”
“three elector nominees”
So four additional differences.
The contest in that state was still legitimately in question (and ultimately flipped although I don’t think that’s significant except to illustrate that it was legitimately uncertain), it wasn’t significant to the overall outcome, It wasn’t an effort to overturn the overall election, and it wasn’t a farce to have the vice president throw the election and install Kennedy as an unelected executive.
This might mitigate the actions of the state-level people somewhat, but the people at the top were still trying to keep Trump in power despite the fact that he lost the election.
