We had people coming to our Foreign Relations Committee and saying, "Oh, we need to arm the allies of Al Qaida." They are still saying this. It is a crazy notion. This is the biggest debate we should be having is is regime change a good idea; has it been a good idea.

President Obama said, oh, we want to make insurance perfect for people, but he added all these regulatory mandates, made it too expensive. Young, healthy people didn't buy it, and the people remaining in the insurance pool were sicker and sicker. That's the adverse selection and the death spiral of Obamacare. And so really we do need to discuss the intricacies of what worked and what didn't work in Obamacare. And I think the better way to do this is to let individuals have the freedom to choose what kind of insurance is best for them. The government doesn't always know best.

The GOP of old has grown old and moss covered.
