Live now on Fox Rubio is framing the contrast very well. Excellent debate and criticism of Florida Governor Christie's support of the stimulus plan. Rubio: "We need someone who can stand up to Obama" Rubio on partisanship: "Lower the corporate tax, lower thwe capital gains tax, reduce the obstacles that make it increasingly hard to do business in America, and I'll be happy to cooperate....but what the Obama administration is attempting to do is fundamentally change America, and we can not cooperate on that."
