WASHINGTON (AP) - Crowds are gathering on the national mall in Washington for this afternoon's rally organized by Comedy Central's Jon Stewart and Stephen Colbert.
It's a festive atmosphere, with signs and stickers proclaiming "relax," "chill out" and "vote sanity."
Organizers insist the so-called "Rally to Restore Sanity and/or Fear" isn't about politics. But supporters and left-leaning advocacy groups are hoping it will rekindle some of the voter enthusiasm for Democrats seen in 2008, particularly among young adults.
One sign in the crowd says "Righties, don't stomp on my head." That's a reference to a Republican rally in Kentucky at which a liberal activist was pulled to the ground and stepped on.
Stewart says the day is about toning down anger and partisan division. On his website, he says "Shouting is annoying, counterproductive and terrible for your throat."
