Steve Benen seems to agree, writing today:
A mature, sensible leader might become introspective, wondering how best to get back on track. Bush has apparently taken to whining about how unappreciated he his. As I recall, Nixon started talking the same way, right before he was driven from office.Buckle up!
This isn’t encouraging. In fact, if Bush starts wondering what he can do to prove everyone wrong about his greatness, this kind of thinking could get scary.
