One of the more bizarre exchanges late in yesterday's debate was between Mike Huckabee and Chris Christie on Social Security and Medicare. The question posed to both of them by Chris Wallace: Governor Christie, I want to engage you and Governor Huckabee in a subject that is a big issue in both of your campaigns, and that is entitlement reform. You say that you — to save the system that you want to raise the retirement age — have to raise the retirement age, and to cut benefits for Social Security and Medicare, and you say that some of the candidates here on the stage are lying. Governor Huckabee says he can save Social Security and Medicare without doing any of that.
