Missouri's 8th congressional district

Missouri's 8th Congressional District is one of 435 congressional districts in the United States and one of eight congressional districts in the state of Missouri. The district encompasses rural Southeast Missouri and South Central Missouri as well as some counties in Southwest Missouri. The district stretches from the Bootheel in the south to the St. Louis southern exurbs of Festus, Hillsboro, and surrounding areas in the Lead Belt; it ranges in the east to counties along the Mississippi River and in the west to counties along the Ozark Plateau near Branson.

The district's largest city is Cape Girardeau. A predominantly rural district, the district votes strongly Republican for national offices. In 2004, President George W. Bush received 63% of the vote in the district over U.S. Senator John Kerry (D-Massachusetts) who clinched 36%. In 2008, U.S. Senator John McCain (R-Arizona) carried the district with 61.92% over U.S. Senator Barack Obama (D-Illinois), who received 36.42%. The district increased the margin for Republicans in 2012 when former Governor Mitt Romney (R-Massachusetts) gained 65.88% of the vote over President Barack Obama's 31.99%.
