In the Massachusetts Senate race, incumbent Scott Brown has “gone negative” on his Democratic challenger, Harvard Law School Professor Elizabeth Warren. Professor Warren gained fame as the godmother of Dodd-Frank’s Consumer Financial Protection Bureau, which as we speak is rendering capitalism safe by engineering financial products that never occurred to any consumer or financial institution and by simplifying mortgage disclosure forms in a mere 1,099 pages. Senator Brown has targeted Mrs. Warren’s phony claims of “Indian” heritage; her $350,000-plus salary at HLS; her work for an insurance company in matters involving (yikes) asbestos; and other trivia. What he hasn’t said and probably won’t say: she is a nag. A scold. An ideologue. An advocate of a nanny state beyond a Swedish socialist’s wildest imagination. A bureaucratic Bruegel who paints an America of victims—pathetic figures in a landscape of unremitting hostility. Also, Professor Warren is an economic idiot.
