In this episode, Joe Lieberman faces a tough challenge in the Democratic primary: an opponent who's actually a Democrat. Then, the Senate eases a ban on importing prescription drugs from Canada. I still think the better solution is to send Canada our sick people. And Ron Suskind stops by to talk about his new book, "The One Percent Doctrine." What a coincidence. That's how much of his book I read. Spoiler alert! This is The Colbert Report.
