In seven states on Dec. 14, a slate of Democratic electors chose Democratic presidential nominee Joe Biden. Republican electors, even though Biden was certified as the winner in the states, also cast votes for President Donald Trump…The phenomenon created seven sets of so-called dueling electors, or alternate slates. Both groups are sending certificates of ascertainment to Congress, which is slated to convene in a joint session on Jan. 6, 2021, to count electoral votes…Dueling electors are highly unusual, but they have happened in U.S. history. The last time was in the 1960 election, when the governor of Hawaii certified electors for Republican Richard Nixon. Democratic electors cast their votes for Democrat John F. Kennedy.
