On July 1, Mississippi Governor Tate Reeves signed HCR 47. It provides that the voters will vote on a proposed constitutional amendment in November 2020 to change the gubernatorial election system. Currently a winner for Governor must not only poll the most votes in November, but must also carry a majority of the state house districts. The amendment would eliminate the provision concerning house districts. If the amendment passes, the winner would be whoever got the most votes, except if no one got 50%, there would be a runoff the following January.

Mississippi elects its governors in November of the odd years before presidential election years, such as 2011, 2015, and 2019.
