Voters head to the polls Tuesday across Mississippi. Early turnout is mixed, with the most people showing up in areas that offer both presidential and congressional primaries. Mississippians are voting on two rare open congressional seats.
In some areas, officials say morning rain may have slowed down participation.
But overall, poll workers are reporting smooth operations.
Campaigning in recent days in Mississippi by Democratic presidential rivals, Sen. Hillary Clinton and Sen. Barack Obama, and their supporters, was anticipated to spur a lot of interest in the primaries. The impact remains to be seen.
