Mississippi Secretary of State Eric Clark predicts that voter turnout Tuesday will be higher than it was for statewide party primaries four years ago. Polls will be open 7 a.m. to 7 p.m.
People are choosing Democratic and Republican nominees for all statewide offices, all 174 legislative seats and regional and county offices.
Clark is the state's chief elections official. He predicts turnout of about 710,000 voters, higher than the nearly 708,000 who turned out for the governor's primary in 2003.
Clark expects turnout will be driven by the hotly contested lieutenant governor's primary on the Republican side and the insurance commissioner's contest on the Democratic side.
Clark says the state has about 1.75 million registered voters.
