Thousands of people fill the National Mall for a political rally.
President Obama is back on the campaign trail trying to rev up support for Democratic candidates in the midterm election. Last week, he held a rally in Los Angeles, which drew more than 37,000 attendees. This Saturday, fans of Jon Stewart and Stephen Colbert will descend on the National Mall in D.C. for the "Rally to Restore Sanity and/or Fear." Supporters of this event, a rejoinder to Glenn Beck's "Restoring Honor" rally in August, say it's time for America to "take it down a notch." Are all these folks just entertaining the choir? Or can this fusion of entertainment and activism create real change? Are bona fide political rallies any more effective at energizing voters?
