Republican frontrunner and Arizona Senator John McCain has virtually secured his party's nomination to the White House riding on a winning streak, capturing California, Arizona, Oklahoma, Delaware, Illinois, Connecticut, Missouri, New Jersey and New York.
McCain is set to emerge with half the 1,191 delegates he needs to clinch the Republican nomination
Meanwhile, former Arkansas Governor and Republican contender Michael Huckabee has revived his chances in the race to the White House by winning contests in Georgia, Alabama, Tennesee, West Virginia and his home state of Arkansas. He came in second in Oklahoma.
"Over the past few days, a lot of people have been trying to say this is a two-man race. Well, you know what, it is. We are in it," Huckabee told his supporters in Little Rock.
Huckabee, who won Iowa primary last month, emerged victorious in the West Virginia, taking away 18 delegates to the Republican National Convention on a day when 24 states are holding primaries and caucuses to later nominate presidential candidates.
Huckabee's wins have come as a blow for former Massachusetts governor Mitt Romney, who scored victories in Utah, Colorado, North Dakota, Minnesota, Montana and Massachusetts, his home state.
According to the Washington Post, Huckabee's strong showing could provide a vital boost to his campaign, which has struggled to attract money and media attention in recent weeks.
