Obama wins N. Dakota Democratic presidential vote

CHICAGO, Feb 5 (Reuters) - Sen. Barack Obama won the North Dakota Democratic caucus on Tuesday, defeating rival Hillary Clinton in his bid to become the party's candidate for U.S. president, media projected.

North Dakota was the 6th state to go for Obama in voting on Tuesday, dubbed "Super Tuesday" because nearly half of the U.S. states are holding contests to choose Republican or Democratic candidates for the November general election. Clinton has won six states so far, projections showed.
