Social Security must be preserved and strengthened. But we need to be candid about the costs and willing to make the tough choices that real reform will require.

Our government has a responsibility to defend our borders, but we must do so in a way that makes us safer and upholds all that is decent and exceptional about our nation.

As to freedom, it is cherished, it is hard to come by, it is hard to hang on to. But freedom without responsibility is chaos, so to those who push the idea that freedom would allow an individual to do anything, anywhere, at any time, I reject, your freedom ends where my ability to raise my family safely begins. So I would urge every American to vaccinate their children and I would reject any effort to stop vaccinations until someone can show me a scientific reason to do so.

Conservatives have a different view of a lot of issues versus our friends on the other side. The election determines how that shakes out.

Iran is part of the problem, not the solution. And the Russian government is ignoring reality.

Marco Rubio, I think, will be president some day. Whether 2016 is his time, time will tell. He embraced immigration reform. He seems to have backed off. I'll let him explain why.

My advice is if we can't replace Obamacare by ourselves, to go to the Democrats and say this. 10% of the sick people in this country drive 90 percent of the cost for all of us. Let's take those 10 percent of really sick people, put them in a federal managed care system so they'll get better outcomes, and save the private sector market if we can't do this by ourselves. That's a good place to start.
