The Vice President’s feisty performance in the debate has his supporters cheering, and others saying he was out-of-control.
Joe Biden laughed, threw up his arms, and kept interrupting Congressman Paul Ryan.
“Oh, now you're Jack Kennedy?” interrupted Vice President Joe Biden.
INSIDE EDITION’s body language expert, Tonya Reiman, revealed the secret clues to what was really going on between the two foes.
“What are you seeing right here?" INSIDE EDITION's Paul Boyd asked of Biden throwing up his arms.
“Ok, so you use these big gestures and what you are doing is really trying to display how strongly you feel about something. And, the finger point. Now we get to the point where he's aggressive and you can even see it in his face,” said Reiman.
She says Biden’s aggressive approach was risky.
"Time after time, we see Biden smiling, laughing, a little smug, a little condescending at times. Is that what you saw?" asked Boyd.
“Yes, he did but again, that's his way,” said Reiman.
Ryan’s furrowed brow was also revealing.
“You noticed quite often through the whole debate, in fact you [could] see these lines on his forehead. He’s always in this state of, 'Believe me! Trust me! Listen to me!,” said Reiman.
Everyone is also talking about how Ryan repeatedly drank water.
“That tells me although he was calm, cool, and collected on the outside, inside, he was struggling. Inside, he was nervous, as most people would be. If you notice, Biden didn't take one sip of water. So he’s used to this platform," said Reiman.
Biden interrupted Ryan an eye-popping 82 times during the 90-minute debate. And he grinned and giggled incessantly.
“I know you're under a lot of duress to make up for lost ground, but I think people would be better served if we don't keep interrupting each other.”
It was "the liveliest Vice Presidential debate we have ever seen," said ABC news correspondant Jon Karl.
"Democrats are psyched that Joe Biden had such a great night," said Rachel Maddow on the Today show.
Fox and Friends host Gretchen Carlson said, "You ever felt that way where you just want to deck somebody? I mean, I'm sorry, I think if you are Paul Ryan last night that's how you feel."
Behind-the-scenes, each side was trying to spin who won.
"I thought it was a decisive victory for the Vice President. To me, it looked like the principal debating the class president,” said political consultant David Axelrod.
Romney Advisor Bay Buchanan said, “The snickering and the loudening and the interrupting is something that's very offensive."
INSIDE EDITION caught up with Romney supporter Donald Trump, and he had praise for both men.
"I thought that both candidates did very, very well. They were really sharp. They were really good. It was a very good debate," said Trump.
The Vice President’s laughter was the most tweeted about moment of the night. 317,603 tweets just about his grin. And did you wonder what Joe Biden was scribbling during the debate? A news photographer took a photo of the Vice President’s handwritten notes:
“Al Q,” meaning Al Qaeda.
And something else you didn’t see on TV. Thousands of people who couldn’t get into the auditorium watched the debate in the open air on the Centre College campus in Danville, Kentucky. Even a statue of Abraham Lincoln wore a pass to the debate.
A CBS poll taken right after the debate said 50% of undecided voters believe Biden won. Ryan received 31% and 19% called it a tie.
And many people felt that tough moderator, Martha Raddatz, did a fantastic job.
“You don’t mess with Martha,” said Jon Karl on Good Morning America.
