The Mississippi Supreme Court has sided with Sen. Thad Cochran, ending a protracted legal battle over the results of the Republican primary runoff election. Chris McDaniel challenged Cochran’s victory in a lawsuit filed in August, claiming Democratic voters illegally participated in the Republican primary.

The court dismissed the suit because it was past the 20 day deadline imposed by common law to challenge an election result. Though the state election laws have changed since the case creating the deadline, the McDaniel campaign argued no such requirement was ever codified.

The state Supreme Court was not persuaded and concurred with the lower court’s dismissal.

State Sen. Chris McDaniel is questioning the integrity of Mississippi’s GOP Senate primary runoff. McDaniel refuses to concede the election to U.S. Sen. Thad Cochran and claims some election activity was unfair, unethical, and illegal.

Evidence suggests hundreds, if not thousands, of voters crossed party lines between primary and runoff elections. Mississippians who voted in the Democratic primary illegally cast votes in the Republican primary runoff.

State election law experts speculate the election results will stand because it is impossible to assume all the irregular votes went to Cochran. Additionally, a strong public policy interest exists in accepting the finality of the runoff election; questioning the integrity of or redoing elections is a slippery slope.

Nevertheless, a conservative group known as True the Vote filed suit in federal court on Tuesday, July 1, against the Mississippi secretary of state and the Republican Party of Mississippi to challenge the results of the runoff.

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.

A June 24 federal runoff has been scheduled for the Mississippi Republican Senate primary. Incumbent Sen. Thad Cochran and state Sen. Chris McDaniel will battle again in a tea party vs. establishment showdown. With 49 and 49.5 percent respectively, neither candidate earned enough of the June 3 vote to secure the party nomination.

McDaniel, running on a platform of change, hopes to unseat the longtime incumbent. Cochran’s congressional tenure began in 1972; he then served three consecutive terms in the House and six consecutive terms in the Senate.
