Clinton was in Irvine to talk local politics, but it didn't take long before he was analyzing President Barack Obama's campaign.
"After his performance last night in the debate, I don't think he needs much help, I thought he did great last night," said Clinton.
Then Clinton went after the GOP nominee, Mitt Romney.
"I don't know if you caught this, he actually finally admitted I was going to get another tax cut if he got elected. In the second debate, he just didn't say it. He said, 'I just want to cut middle class taxes but wealthy people will still pay the same percentage.' Math 101: If I pay the same percentage, and all of you get a tax cut, I get one too. It's arithmetic," said Clinton.
Clinton endorsed five Democratic congressional candidates who are locked in tight races. Among them are state Assemblywoman Julia Brownley, who's running against Republican state Sen. Tony Strickland in Ventura County; state Sen. Alan Lowenthal, who's opponent is Long Beach City Councilman Gary DeLong; and educator Mark Takano, who's taking on Riverside County Supervisor John Tavaglione.
"If you want not only to re-elect President Obama, but see him in a position to enact a second term agenda that will create a 21st Century American prosperity, you have to vote for them," Clinton told the crowd.
Thousands showed up to hear the former president speak. Many of them are students who will be voting for the first time.
"He's a rockstar and everyone here at UCI was very excited," student Rudy Salvio said about Clinton.
