WASHINGTON (AP) — The tea party has suffered two major losses in Tuesday's primary voting.

In Mississippi, six-term Republican U.S. Sen. Thad Cochran has barely held off tea party challenger Chris McDaniel.

Cochran made a last ditch appeal to Democratic-learning black and union voters.

In Oklahoma, Rep. James Lankford has outpolled tea party favorite T.W. Shannon for an outright win of the Republican nomination for the U.S. Senate seat vacated by Tom Coburn.
