Huckabee wins W.Va.

Republican Mike Huckabee scored the first Super Tuesday victory, winning all 18 delegates at stake in West Virginia.

The former Arkansas governor won with the support of 52 percent of the state's GOP convention delegates on the second round of balloting. Former Massachusetts Gov. Mitt Romney came in second with 47 percent of the vote, and Sen. John McCain was backed by 1 percent of the delegates.

Romney was ahead in the first round of voting in Charleston but failed to get the majority needed to win.

With 24 states and American Samoa holding primaries or caucuses, Super Tuesday is virtually a national primary day and a pivotal day in the Democratic and Republican races for the White House.

Some of the biggest prizes of the primary season -- California, New York, Illinois, New Jersey, Missouri and Georgia -- are up for grabs.
