Mississippi voters are choosing a Republican nominee for U.S. Senate and the Democrat nominee for U.S. House for the 3rd Congressional District.The polls are open until 7 p.m.
Douglas MacArthur Magee and Dennis Quinn are seeking the Democratic nomination for U.S. House District 3. The winner will advance to the Nov. 4 general election against incumbent Rep. Gregg Harper. The campaign has been quiet, without the extensive advertising of the Senate race.
Voting Tuesday will end one of the state's hardest fought and most expensive races in decades, between incumbent Sen. Thad Cochran and state Sen. Chris McDaniel.
McDaniel finished 1,418 votes ahead of Cochran in a three-person primary earlier this month, but nobody received a majority to win.
The only voters banned from casting a Republican ballot Tuesday are those who voted in the Democratic primary June 3.
The Republican nominee advances to the general election to face the Democratic nominee, former U.S. Rep. Travis Childers, and the Reform Party's Shawn O'Hara, who has run for dozens of offices the past two decades.
