Mississippi legislators imposed no new limits on the election process during their recently ended session, but this state already had some of the strictest voting laws in the U.S. Widespread early voting? Not in Mississippi. This state has a limited number of reasons for people to cast absentee ballots. Some states have drop boxes where early voters can leave their ballots. Mississippi does not have drop boxes, which means people mailing back absentee ballots have to deal with the uncertainties of the U.S. Postal Service.
