In total, six Republicans and three Democrats were elected. A total of 1,920,675 votes were cast, of which 1,103,290 (57.44 percent) were for Republican candidates, 708,064 (36.87 percent) were for Democratic candidates, 92,485 (4.81 percent) were for Libertarian Party candidates, 8,759 (0.46 percent) were for Constitution Party candidates, 7,193 (0.37 percent) were for an independent candidate and 884 (0.05 percent) were for write-in candidates.

## District 1

The 1st district included Ferguson, Florissant, Hazelwood, Spanish Lake, and parts of St. Louis and University City. The district's population was 54 percent black and 40 percent white (see Race and ethnicity in the United States census); 83 percent were high school graduates and 24 percent had received a bachelor's degree or higher. Its median income was $41,404. In the 2008 presidential election the district gave 80 percent of its vote to Democratic nominee Barack Obama and 19 percent to Republican nominee John McCain.
Democrat William Lacy Clay, Jr., who took office in 2001, was the incumbent. Clay was re-elected in 2008 with 87 percent of the vote. In 2010 Clay's opponent in the general election was Republican nominee Robyn Hamlin, an insurance agent. Libertarian Party nominee Julie Stone also ran. Candice Britton also sought the Democratic nomination. Martin Baker and Marshall Works also sought the Republican nomination. Robb Cunningham also sought the Libertarian nomination.
Clay raised $693,370 and spent $635,944. Hamlin raised $23,930 and spent $24,012. Britton raised $1,813 and spent $2,026.
Prior to the election FiveThirtyEight's forecast gave Clay a 100 percent chance of winning and projected that he would receive 74 percent of the vote to Hamlin's 23 percent. On election day Clay was re-elected with 74 percent of the vote to Hamlin's 24 percent. Clay was re-elected in 2012, again over Hamlin, and in 2014.
