These two analyses suggest--Im going to regret writing this--that the confirmation will be a cakewalk. According to the NYTs Linda Greenhouse, Roberts hit the days rhetorical high point. And the WaPos Dan Balz offers evidence from Notre Dames Richard Garnett (for more, go here) that Roberts, at least, has his eye on the prize--not just being confirmed, but making the case for a self-consciously limited judicial role in a regime characterized by the rule of law. (For more on this, see Lucas Morels most excellent post.)
For other analysis and interesting back story, go here (Specters confused unreliability), here ("elections matter"), here (Lee Otis vs. Nan Aron), and here (what it means to be the "political" deputy SG). Obviously, also, Bench Memos and Power Line should be among your bookmarks.
