Not since 1912–when 8 Republican electors defected and voted for Nicholas Murray Butler instead of Vice Presidential candidate James S. Sherman, who died before the election–has anyone lost more electors than Mrs. Clinton. Sherman was President William Howard Taft’s vice president and they were both running for re-election.
Not since 1896, when two parties, the Democratic Party and the People’s Party, ran William Jennings Bryan as their presidential candidate has a candidate lost as many electors in the Electoral College as Mrs. Clinton did in 2016.
