In a tight race Tuesday, Mississippi Sen. Thad Cochran secured the GOP Senate nomination with 50.8 percent of the vote. Cochran battled tea party candidate Chris McDaniel in a federal runoff after neither candidate carried enough votes in the June 3 primary to capture the nomination.

Although McDaniel’s campaign has not made a decision whether to challenge the results, Cochran’s win ends a somewhat bizarre and expensive political battle between the two candidates.

In November, Cochran will face Democrat Travis Childers; if elected, Cochran will serve a seventh consecutive Senate term.
