WASHINGTON – In the shadow of the Capitol and the election, comedians Jon Stewart and Stephen Colbert entertained a huge throng Saturday at a “sanity” rally poking fun at the nation’s ill-tempered politics, its fear-mongers and doomsayers.

“We live now in hard times, not end times,” Stewart said after all the shtick.

Part comedy show, part pep talk, the rally drew together tens of thousands stretched across an expanse of the National Mall, a festive congregation of the goofy and the politically disenchanted. People carried signs merrily protesting the existence of protest signs. Some dressed like bananas, wizards, Martians and Uncle Sam.

Stewart, a satirist who makes his living skewering the famous, came to play nice. He decried the “extensive effort it takes to hate” and declared “we can have animus and not be enemies.”

Screens showed a variety of pundits and politicians from the left and right, engaged in divisive rhetoric. Prominently shown: Glenn Beck, whose conservative Restoring Honor rally in Washington in August was part of the motivation for the Stewart and Colbert event, called the Rally to Restore Sanity and/or Fear. It appeared to rival Beck’s rally in attendance.

As part of the comedic routine, Stewart and his associates asked some in the audience to identify themselves by category, eliciting answers such as “half-Mexican, half-white,” “American woman single” and “Asian-American from Taiwan.”

“It’s a perfect demographic sampling of the American people,” Stewart cracked to a crowd filled with mostly younger whites. “As you know, if you have too many white people at a rally, your cause is racist. If you have too many people of color, then you must be asking for something – special rights, like eating at restaurants or piggyback rides.”

With critical congressional elections looming Tuesday, Stewart and Colbert refrained from taking political sides on stage, even as many in the crowd wore T-shirts that read “Stewart-Colbert 2012.”

Stewart sang along as Jeff Tweedy sang that America “is the greatest, strongest country in the world. There is no one more American than we.”

Kid Rock and Sheryl Crow also performed, singing if “I can’t change the world to make it better, the least I can do is care.”

The idea was to provide a counterweight to all the shouting and flying insults of these polarized times. But there were political undertones, too, pushing back against conservatives ahead of Tuesday’s election.

Signs read “I wouldn’t care if the president was Muslim” and “Righties, don’t stomp on my head,” a reference to a Rand Paul rally in Kentucky at which a liberal activist was pulled to the ground and stepped on.

Colbert, who poses as an ultraconservative on his show, played the personification of fear at the rally. He arrived on stage in a capsule like a rescued Chilean miner, from a supposed underground bunker. He pretended to distrust all Muslims until one of his heroes, basketball great Kareem Abdul-Jabbar, who is Muslim, came onstage.

“Maybe I need to be more discerning,” Colbert mused. He told Stewart: “Your reasonableness is poisoning my fear.”

Stewart said the day was about toning down anger and partisan division. “Shouting is annoying, counterproductive and terrible for your throat,” he said on his website.

Comedy Central’s park permit anticipated a crowd estimated in advance at 60,000.
