Blogging is scarce at the moment because of a pressing deadline.
However, in case you don't read neo-neocon, I definitely suggest checking out her recent posts on "change" -- evolution, sometimes radical, in views on political issues. A mind is a difficult thing to change is the latest in the author's continuing story of her own political journey. There are also several recent posts on other changers, including Guardian writer Jonathan Freedland. All these are admittedly changes from "left" to "right," at least on foreign policy issues. But I think they're quite fascinating, particularly in view of that recent study about how resistant people are to facts that contradict their strongly held views.
