Social justice movements take more than clicking a link on an online petition, says Paul Rogat Loeb, author of Soul of a Citizen: Living with Conviction in Trying Times. Making change requires getting out in the streets, going door-to-door, and talking to other people face to face.

Loeb came to see us in studio to talk about the new edition of his book, about Barack Obama, Glenn Beck, cross-movement alliances and how the Left can reach out to the tea party crowd.
