The Mississippi Valley is a superregion consisting of the regions of the Midwest and the Gulf Coast. It consists of the states of Minnesota, Iowa, Missouri, Arkansas, Louisiana, and Mississippi., and stretches from Canada's southern boarder (at western Ontario) in the north to the Gulf of Mexico in the South. It shares a boarder with the superregions of the Heartlands, and Dixie on the east, and Big Sky Country, and the Sunbelt in the west. It is named after the Mississippi River.
The Mississippi Valley is known as one of several swing regions in the country. In other words, both Democrats and Republicans have an equal chance of getting elected. However, the superregion, and both regions, lean slightly in favor of Democrats. Both the Midwest and the Gulf Coast, traditionally has one senator from each party representing them. However, that changed in 2016 when the Midwest elected two Republican senators (Andrew Graham, and Ron Casey, and the Gulf Coast elected Democrat Evelyn Breaux to serve alongside fellow Democrat Red Blanchard. On a superregional level, there have been two Democratic governors (Carter Glass (2009-2013), and Johnny Green (2013-2015)) who have served for a total of six years, and one Republican governor (Brian Murphy)who has served for two years, but was reelected to a full four year term in 2016.
