Even Ted Cruz's critics seem to concur on one point: whatever else you might say about him, the man is very smart. Mother Jones magazine has called him the “thinking man's tea partier.” Josh Marshall, in a mostly withering assessment, made the same obligatory concession to his being an “incredibly bright guy.” Jeffrey Toobin’s recent, ostensibly critical New Yorker profile of Cruz is full of quotes about his being “the smartest guy in the room,” his “sophisticated” constitutional views, and the “extraordinary” erudition of his senior thesis.
