Republican incumbent: Thad Cochran
Democratic candidate: Erik Fleming
Cochran, 70, has represented Mississippi in the Senate since 1978. He had previously served three terms in the U.S. House.
Fleming, 43, served in the state House of Representatives from 1999 to 2008. He won the Democratic U.S. Senate primary two years ago, but lost the general election to Trent Lott.
As I explained here, this is one of two U.S. Senate elections in Mississippi this year.
Rasmussen Reports shows a 27-point Cochran lead in a June poll.
This campaign seems to be overshadowed by the much-closer race in the special election for the state's other Senate seat. While the Democrats are looking at a possible gain in the special election, it looks as though Cochran is likely to keep his seat in the Republican column.
