McCain wins Oklahoma Republican presidential vote

DALLAS, Feb 5 (Reuters) - Arizona Sen. John McCain won the Oklahoma Republican primary on Tuesday, handing rival Mitt Romney another blow in the race to become the party's candidate for the November U.S. presidential election, media projected.

Oklahoma was the 6th state to go for McCain in voting on Super Tuesday, so called because nearly half of the U.S. states are holding contests to choose Republican or Democratic candidates for the November general election. Former Massachusetts Gov. Romney has won one state so far in Super Tuesday voting, projections showed.
