This just about sums it up:
Nothing about health care. Nothing about how long they plan to stay in Iraq. Nothing about the impending attack on Iran. Nothing about Middle East policy in general. Nothing about energy policy. Nothing about education. Nothing about the mortgage mess. And of course, nothing about how they would restore Constitutional law.
Not entirely fair: they did discuss Iraq briefly. I don't think the absence of healthcare represents bias on the part of CNN, so much as a lack of interest in the GOP base. It's clear to me that the two major issues for them are immigration and spending. In general, it felt like a debate from a party that expects to be in the wilderness for a while. And they sure deserve to be.
