Stewart, Colbert rallies: who's going?

 One is much more popular than the other

Jon Stewart and Stephen Colbert will draw thousands to their Washington, D.C. rallies next month.

But, if Facebook RSVPs are any indication, one will be much more popular than the other.

Colbert's "March to Keep Fear Alive" has 38,325 (and counting) attending, 13,722 not attending, 14,962 attending and 49,296 awaiting reply.

Stewart's "Rally to Restore Sanity," meanwhile, has 97,770 confirmed, 265,180 awaiting reply and 50,180 maybe attending.

Perhaps this number discrepancy is reflected in their ratings. Earlier this year, "The Daily Show" was averaging 2 million viewers a night, and "Colbert Report" was drawing in 1.4 million.

The Comedy Central hosts' rallies will take place October 30 on the National Mall -- about two months after Glenn Beck's "Restoring Honor" event, which he held on August 28, the 47th anniversary of Martin Luther King's "I Have a Dream" speech. It attracted between 87,000 and 300,000 attendees, depending on who you ask.
