John and Joe welcome Paul Vallas to the show!

Paul Vallas is best known for his innovative work in public education — as superintendent of schools in Chicago and in the all-charter school system in New Orleans — and (most recently) his impressive campaign for Mayor of Chicago (he got 48% of the vote, running against the mighty machine of the Chicago Teachers Union). Joe Klein, who has been campaigning in print against teachers unions for the better part of four decades, conducted the lion's share of the interview.
