An estimated 215,000 people attended a rally organized by Comedy Central talk show hosts Jon Stewart and Stephen Colbert Saturday in Washington, according to a crowd estimate commissioned by CBS News.
The company AirPhotosLive.com based the attendance at the "Rally to Restore Sanity and/or Fear" on aerial pictures it took over the rally, which took place on the Mall in Washington. It has a margin of error of plus or minus 10 percent.
CBS News also commissioned AirPhotosLive.com to do a crowd estimate of Glenn Beck's "Restoring Honor" rally in August. That rally was estimated to have attracted 87,000 people. Amid criticism from conservatives that the estimate was low, CBS News detailed the methodology behind it here (we're liberals who hate conservatives).
The only rally that Stewart/Colbert can accurately claim to be bigger than is the Communist "One Trashy Nation" earlier this month.
