The presidential election has long been declared, but a historic tradition remains: casting the official electoral college ballots.
South Dakota Gov. Dennis Daugaard, Lt. Gov. Matt Michels, Attorney General Marty Jackley and the state's electoral college electors will cast the ballots at noon Monday in the governor's reception room in the State Capitol.
Secretary of State Jason Gant says it's "an honor to witness this historic event."
South Dakota voters elected Republican Mitt Romney as president with nearly 211,000 votes. President Barack Obama got 145,000 votes.
Obama won the national race handily by the electoral college tally, with 332 electoral votes to Romney's 206. South Dakota has three electoral votes.
