In her acceptance speech at this year's Republican convention, Sarah Palin got a big laugh with this description of Barack Obama's experience as a "community organizer" in Chicago. Rudy Giuliani and other Republicans did too. Now it appears that the joke is on the Republicans. For almost two years, Obama had been organizing the communities that produced record turnouts on election day. But he also married that time-honored strategy to 21st century technology in a campaign described as looking like Facebook. We hear how a million volunteers with computers and cell-phones advanced the art of campaigning, by combining the old with the new.
