What time do Super Tuesday polls open and close? Key voting hours to know for 2024

Washington — Voters in 15 states are poised to cast their ballots for the 2024 Republican presidential nomination on Super Tuesday, with poll opening and closing times varying by state.

There are 13 primaries and two caucuses set to take place, with 874 delegates at stake for the two GOP candidates still in the race — former President Donald Trump and former South Carolina governor and U.N. Ambassador Nikki Haley. 

Super Tuesday is the biggest voting day of the 2024 presidential election, and Trump comes into it with wins in all but one of the Republican contests held so far — Haley notched a win in the District of Columbia's primary on Sunday— and a commanding lead in the delegate race.
