A combination photo shows Tea Party candidate Chris McDaniel (L) attending a rally in Madison, Mississippi and Republican U.S. Senator Thad Cochran campaigning in Pass Christian, Mississippi June 19, 2014. Voters in Mississippi will decide on Tuesday whether to retire a veteran U.S. senator who has steered billions of government dollars to his impoverished state, in the latest showdown between the Republican establishment and its insurgent Tea Party wing. The election, a runoff between Senator Thad Cochran and challenger state Senator Chris McDaniel, has become a multimillion-dollar referendum on the direction of the Republican Party.
