On February 14, Mitt Romney officially endorsed McCain and asked his approximately 280 delegates to support him at the national convention. If all or most of Romney's delegates backed McCain, it would give him nearly enough to win the nomination, with several large states still yet to vote. Despite these developments, Huckabee vowed to stay in the race. "I may get beat, but I'm not going to quit," he said. A few days later, McCain was endorsed by former President George H.W. Bush, in a move intended to shore up his support among base party elements.
