Weather appeared to be a major factor in voter turnout early Tuesday in Mississippi.
Heavy rains kept people away from polls in some areas, even in parts of Mississippi with highly contested congressional races.
Voting was brisk in areas where the weather was fair, especially in two congressional races in which Democratic incumbents were facing tough challenges from Republican state lawmakers.
Jared Allen, a National Weather Service meteorologist, said most of Mississippi would get rain Tuesday, though it had not reached some areas in the south and northeast by mid-morning.
Early turnout reports in Alabama were mixed. Election officials in Mobile and Montgomery counties said phone traffic from precincts indicates a brisk turnout early Tuesday, but it was reported to be light in downtown Birmingham.
With the governor's office atop a long ballot, turnout is expected to be good, but not as heavy as in a presidential election.
The secretary of state's office reports that slightly more than half of Alabama's voters traditionally turn out for an election for governor. The turnout in the last five elections for governor has ranged from nearly 51 percent to 58 percent.
