Recap of the Popular Vote
James Monroe won a nearly unanimous election victory in the popular vote of 1820, having the support of the dominant Democratic Republican Party and the disappearing Federalist Party. He won all 161 electoral votes available through the popular vote.
The vote in the nine states choosing Presidential Electors through the legislatures was identical - Monroe won all 72 Presidential Electors, four of which were Federalists. States so choosing were AL, DE, GA, IN, LA, MO, NY, SC, and VT.
Casting the Electoral Vote
The Presidential Electors assembled in their various state capitals on 12/6/1820. The first duty in each state was the selection of a chairman; former President John Adams was chosen in Massachusetts, and former Gov. William Plumer was chosen in New Hampshire. The next step was the filling of vacancies. In Massachusetts, two districts failed to make a choice (one district had a tie), and two Electors failed to appear. After filling the vacancies, the Electors cast the electoral votes. James Monroe received 231 votes to one for SOS John Quincy Adams. The vote for Adams was cast by Plumer (though whether he disapproved of Monroe or whether he believed only Washington deserved a unanimous election has since been debated). VP Tompkins was re-elected with 218 votes; Plumer voted for Richard Rus
