One of the best grad students ever?

An excerpt from Robert Samuelson's column: "I cannot detect powerful convictions in Obama. He seems merely expedient in peddling his convenient conflicts. He strikes me as a super-successful graduate student: the brightest, quickest, most articulate guy in the seminar. In his career, he has advanced mainly by talking and writing -- not doing -- and may harbor a delusion common to the well-educated: that he can argue and explain his way around any problem."
