McCain wins Washington Republican presidential vote

SEATTLE, Feb 19 (Reuters) - Arizona Sen. John McCain won the Washington vote to select a U.S. Republican presidential candidate on Tuesday, moving closer to capturing the party's nomination for the November general election.

Front-runner McCain is almost certain to be the Republicans' presidential candidate after his main opponents bowed out of the race, but he continues to face a challenge from former Arkansas Gov. Mike Huckabee, who trails badly but has pulled off embarrassing upsets in some states. (Reporting by John Whitesides, editing by Lori Santos)
