1) Jon Chait at TNR. While he might misread why large editorial board's have endorsed McCain (I'd guess more to do with his openness to the press and his slightly less insane views on immigration and religion than with his 'conservative principles'), I think his reading of the impossibility of predicting what a McCain presidency would look like is mostly right.
The penultimate 'graph: It is a truly impressive skill McCain has--the ability to adopt new beliefs and convince his new allies that his conversion is genuine (or, at least, irreversible) while simultaneously strengthening their belief in the immutability of his principles. I suspect that, in the end, it will come to tears for McCain's new allies--just as it has for most of those, including me, who thought they had a bead on him in the past. But, really, who knows?
