If you missed Rachel Maddow's interview with Tom Ridge tonight, you should go watch it all. But here's the highlight: her stern riposte to Ridge's claim that invading Iraq was the right thing to do. The whole interview is remarkable for her politeness and good humor in the face of some pretty unconscionable double-talk on Ridge's part, but also for doing one thing that TV journalists too seldom do: sticking to her guns and speaking truth to power.
