WASHINGTON (AP) -- Tea party hopefuls have suffered two major defeats in Tuesday's primary voting.
In Mississippi, six-term Republican incumbent Sen. Thad Cochran edged out tea party favorite Chris McDaniel.
With 99 percent of precincts reporting, Cochran had 51 percent to McDaniel's 49 percent. McDaniel outpolled Cochran just three weeks ago. Both fell short of the majority needed in the initial primary round. In a last ditch effort, Cochran appealed to Democratic voters, the majority of which in the state are black.
In another setback for the tea party, two-term Rep. James Lankford of Oklahoma won the GOP nomination in the race to succeed Sen. Tom Coburn. He defeated T.W. Shannon, a member of the Chickasaw Nation and the state's first black House speaker. Shannon had the backing of presidential candidate Sarah Palin and Texas Sen. Ted Cruz.
In Colorado, former Rep. Bob Beauprez (boh-PRAY') won the crowded gubernatorial primary that included 2008 presidential candidate Tom Tancredo.
In Maryland, Lt. Gov. Anthony Brown won the Democratic primary for governor. If elected in the Democratic-leaning state, Brown would make history as the state's first African-American governor.
