McCain projected to win Wisconsin Republican primary

MILWAUKEE (Reuters) - Sen. John McCain won the Wisconsin vote to select a Republican presidential candidate on Tuesday, moving closer toward locking up the party's nomination after his leading rivals bowed out of the race, U.S. media projected.

McCain, the overwhelming front-runner, is all but certain to win the Republican presidential nomination, but continued opposition from former Arkansas Gov. Mike Huckabee has forced him to keep campaigning and spending his resources to avoid an embarrassing loss.
