Sen. John McCain cemented his position as the Republican front-runner with his win in the California primary -- the most delegate-heavy state up for grabs on Super Tuesday.
His was victorious in nine states, despite a low percentage of conservative Republicans voting for him: While more than six in 10 GOP primary voters said they were conservatives, only 31 percent of them voted for McCain, according to ABC News' poll analysis.
But McCain did better-than-expected among independents and moderates, and even scored some crossover Democrats.
While many of the biggest states on Super Tuesday went to McCain's camp, former Arkansas Gov. Mike Huckabee also picked up key wins in the South -- including Alabama, Tennessee and Georgia, as well as his home state.
McCain, speaking to a cheering crowd Tuesday at his Phoenix, Ariz., headquarters, said that he "doesn't mind" being the Republican Party front-runner. The road ahead is still a long one, he added.
The results were more disappointing for former Massachusetts Gov. Mitt Romney, who won his home state, Colorado, Minnesota and the small prizes of Montana, Utah and the North Dakota and Alaska caucuses. But in a speech delivered from his campaign headquarters in Boston, Romney spoke passionately to a crowd of cheering supporters.
"One thing that is clear is that this campaign is going on!" said Romney.
Conservative voters favored Romney -- the former governor won 38 percent of their support compared to McCain's 31 percent and Huckabee's 23 percent.
Earlier in the evening, Huckabee told a crowd at his own campaign's headquarters in Little Rock, Ark., "Over the past few days a lot of people have been trying to say this is a two-man race, but you know what? It is, and we're in it!"
Exit polls showed that Huckabee's success in Arkansas and Alabama was a result of a remarkable turnout by evangelicals, who made up 75 percent of the Republican primary voters in Arkansas. Huckabee, an ordained Baptist minister, won the evangelicals by 17 points, beating McCain by more than 4-1. In Alabama, 77 percent of the voters were evangelicals, 47 percent of which went to Huckabee and only 35 percent voting for McCain.
McCain won New York, Connecticut, Delaware, Illinois, New Jersey, Oklahoma and his home state of Arizona. The senator also took Missouri's Republican primary in what was a close three-way race throughout the evening.
With these results, McCain took six winner-take-all states, garnering 180 delegates in Connecticut, New Jersey and New York alone.
McCain is currently far ahead in the race for delegates with a total of 561. Romney has 222 and Huckabee has 172.
Earlier Tuesday, it was Huckabee -- a candidate widely considered to be in the race as a spoiler, and not a contender -- who won the first contest of the day.
Huckabee garnered 52 percent of the vote to win the West Virginia caucus. Huckabee will receive at least 18 of the state's 27 delegates as a result of his win.
West Virginia's convention setup is unlike many state systems, in that two rounds of voting determine the winner. The first round went to Romney, spurring the supporters of McCain — realizing the Arizona senator wasn't going to win — to switch their votes to Huckabee instead.
All three campaigns exchanged words on whether McCain and Huckabee had brokered a "backroom deal" to ensure Romney's defeat. While McCain and Huckabee both denied the allegations, Romney's camp remained convinced a deal had been made.
