Romney wins N.Dakota Republican presidential vote

CHICAGO, Feb 5 (Reuters) - Mitt Romney won the North Dakota Republican caucus on Tuesday, scoring a victory over rival John McCain in his bid for the party's U.S. presidential nomination, U.S. media projected.

North Dakota was third state to go for Romney 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. McCain, an Arizona senator, has won six states in Super Tuesday contests, while former Arkansas Gov. Mike Huckabee has won three.
