(CNN)Sen. Marco Rubio had only kind words for potential Republican presidential rivals Jeb Bush and Mitt Romney on Wednesday, but he argued if he runs he'll have better credentials to offer than the two former governors. "I believe that the central obligation of the federal government ... is providing for the national security," he said during a breakfast briefing for reporters hosted by the Christian Science Monitor. "The next President of the United States needs to be someone who has a clear vision of American's role in the world." "For governors that's going to be a challenge, at least initially," Rubio added, "since they don't deal with foreign policy on a daily basis."Marco Rubio praised Jeb Bush and Mitt Romney, but argued governors don't have the foreign policy chops needed for the White HouseHe said he'll choose between running for the White House or reelectionRubio might have some clarity on the decision during his weekend confab with donors and strategists
And with the GOP primary field shaping up to include potentially a dozen prominent _, Rubio's foreign policy experience could potentially offer him a needed boost to break away from the pack.
