Mr. Hundt, who now works for consultancy McKinsey and frequently contributes to the popular blog Talking Points Memo, is an ardent supporter of Barack Obama and has been advising the Senator and newly- annointed Democratic nominee, on technology and telecommunications policy. He will be debating Bush 43’s FCC chair, Michael Powell, on June 10 — one of the early proxy battles between Obama and McCain, where the technology policies advocated by the two candidates will be on display.
