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.
