Thad Cochran is telling supporters that he will continue to ensure Mississippi's voice is heard in Washington if he's elected to a seventh term in the U.S. Senate.
His challenger in Tuesday's Republican primary runoff, Chris McDaniel, is calling for change on Capitol Hill.
Both candidates made appearances Monday in Meridian, Cochran at his campaign headquarters and McDaniel at Jean's Restaurant.
The two meet in the Republican runoff Tuesday. Polls will be open 7 a.m. to 7 p.m.
U.S. Sen John McCain and other supporters of Cochran Monday in Jackson played up his support for the military.
Five Mississippi Republicans, State Auditor Stacey Pickering, Lt. Gov. Tate Reeves, U.S. Rep. Gregg Harper, U.S. Sen. Roger Wicker and Gov. Phil Bryant, renewed their endorsements of Cochran.
McCain called on other veterans and military members to vote for Cochran, saying the longtime senator has been a steady ally of military spending and readiness.
McDaniel has his share of political celebrity support including Rick Santorum and Sarah Palin, as well as conservative talk show hosts Laura Ingraham, Sean Hannity and Lars Larson.
