Mississippi voters are helping choose the president and are electing five federal officials and five state appellate judges.
Polls are open 7 a.m. to 7 p.m. Tuesday.
Voters won't be required to show identification at the polls because the federal government hasn't decided whether to approve the state's proposed voter ID law.
The state has six electoral votes for president, with 270 needed to win.
One U.S. Senate race will be on ballots statewide.
Each of the four U.S. House districts has a race.
The northern Supreme Court district has one contested race. The central district has two races, one contested and one with only one candidate.
The southern Supreme Court district has one contested race.
In the Delta and most of Jackson, there's a Court of Appeals contest.
Many local races are already decided. But there are some contested races in east Mississippi.
