Signs of the apocalypse: National Review Online’s Donald Luskin describes himself as an “adviser to John McCain’s campaign, though as far as I know, the senator has never taken one word of my advice.” This is the same Donald Luskin who UC-Berkeley economist Brad DeLong has repeatedly described as “the Stupidest Man Alive” for his shaky grasp on basic economics (like McCain circa 2007-2008, Luskin is a believer in the myth that tax cuts raise revenue). My primary exchange with Luskin was, shall we say, not inspiring. I wouldn’t let him advise me on balancing my checkbook.
