Niall Ferguson In Newsweek: "Obama's Gotta Go." This article is very strong when it comes to the mediocrity (at best) of Obama's record. It gets weaker when it starts celebrating the alternative, and with the claim that "Ryan psychs Obama out." (I remember the same exact claim re Palin four years ago; even if true, it wasn't a particularly consequential effect.) But since so much of the election is now about Ryan, Ryan, Ryan (or today, worse about somebody named Akin about whom I hope to never hear again), it's valuable to have some attention paid to just what the incumbent has done and not done.
UPDATE: Ferguson's piece gets some pushback here. And Ferguson has more here.
