Voters in 24 states today are casting their ballots in primary elections for the office of the President of the United States. With more states voting than ever before on "Super Tuesday," presidential primary ballots today will deliver 1,681 delegates to Democratic candidates, and 1,023 to Republicans. The total number of delegates needed to win each party's nomination is 2,025 for Democrats and 1,191 for Republicans. The Washington Post reports that "with Super Tuesday nominating contests taking place from New York to California, the candidates made last-minute appeals for support in the biggest round of primary voting in U.S. political history before scattering to their home states to cast their own ballots and await returns."
