The presidential debate Wednesday night was the most tweeted about event in political history, and, it's still being talked about this morning.

Jon Stewart, appearing on Good Morning America today to tout his own upcoming debate (Saturday in Washington) with Bill O'Reilly, assessed President Obama and Mitt Romney.

"Ithink we can all be satisfied in this election that no matter whathappens, we're going to have an incredibly good-looking president,"cracked Stewart. "That was some beefcake up there last night. The two ofthem. And when they take this thing into the swimsuit competition...."

He continued: "There's not a country in the world ... put those two up against what? (German Chancellor Angela) Merkle?"

Headded that now, "Obama realizes, 'Oh, pre-season's over. I shouldprobably familiarize myself with my presidency and learn some of thevarious numbers and things that go along...' I thought he had a verydifficult night. And I'm concerned he may not re-elect us."

The debate night was the most tweeted about event in political history, and stars weighed in.

AlecBaldwin: "Obama is a potentially great man who remains mildlyuncomfortable in public life. Mitt is a gifted off-shore money tycoonand tax preparer." And, "2 judge these men from these debates isridiculous. Obama is a 21st Century Democrat. He wants as much change ascorp America will allow."

Mia Farrow: "I love great schools I love Big Bird I like coal Not feeling the coal-love"

Lady Gaga:"I believe its important to note before this begins that Romney is amillionaire and paid well below the average tax rate, paying only13.9%."

Samuel L. Jackson: "What future generations is Mitt theguardian of?! I think dude just wants to add Leader Of The Free World tohis resume'!"

Dean Cain, who tweeted a lotabout the debate: "Romney looks like the next President to me. I'm looking forward to next year. #Romney"

MichaelMoore: "Ok, here's my optimistic tweet: Romney didn't convince a singleObama voter to change their vote. But O needed to fire up the base. Notdone."

Bill Maher: "my rating: Romney won the debate, Obama hadthe facts on his side, and Lehrer sucked. Next debate, get@SethMacFarlane to host!"

Rob Lowe: "Watched a lot of debates, that was a real blood-letting. #POTUSwiffs#Mittenssticks

Justas Big Bird became a trending topic the instant Mitt Romney brought himup, moderator Jim Lehrer got his share of attention, from criticism toparody to sympathy.

Julia Louis-Dreyfus: "What r u doing, Jim Lehrer? What r u doing?!"

Al Roker cracked: "I hope Jim Lehrer gets the license plate of the truck that drove over him in this debate."
