Washington (CNN) -- Sen. Marco Rubio, who is considering a presidential run, said Sunday that President Barack Obama has thrown away valuable leverage to bring about political changes in Cuba. He also took another opportunity to attack his potential opponent for the Republican presidential nomination, Kentucky Sen. Rand Paul, who agrees with Obama's decision to switch course on Cuba. The most vocal Republican leading the fight against Obama's rapprochement with Cuba insisted again that Obama's new policy won't bring democracy to the island. "My opposition to what the President has done is it won't do anything to further that cause (of democratization)," Rubio said on NBC's "Meet the Press." "There has to be some reciprocal opening on their part toward democracy and there was none in this engagement."
