Mississippi’s Constitution says that no one can be elected Governor without both receiving the greatest number of votes, and carrying a majority of state house districts. A lawsuit is currently pending in U.S. District Court to overturn that law. On August 19, the voter-plaintiffs who filed the case filed this 40-page brief. The case is McLemore v Hosemann, s.d., 3:19cv-383.
The Mississippi Constitution says that if no candidate both gets the most popular votes and also carries a majority of the state house districts, then the legislature chooses the Governor.
