At least, according to Mitt Romney. When Mitt withdrew from the presidential race, he said that "in this time of war" it was important to have a strong leader, like McCain. Staying in the race would keep McCain bogged down fighting the primary election, and would keep him from focusing on winning the general election. That lack of ability to focus would in turn make it more likely that Obama or Clinton would win, two people Romney says are weak on the war.
Well, doesn't that same logic apply to Huckabee? Isn't his staying in the primary race keeping McCain from consolidating and getting ready for November? Huckabee must hate America, and must want the terrorists to win.
