9,300 supporters, many of them young voters, packed The Palestra to hear from the Democratic heavy hitter who made other stops in Pittsburgh, Blue Bell, Montgomery County, and Scranton to make his case for the President's re-election.
"I want you to vote your hopes and not your fear. I want you to imagine what America can be like 10 years from now and I want you to go out and vote President Barack Obama president for four more years," Clinton said.
The line to get in stretched for blocks in University City with young and energized supporters of President Obama.
"He's just such an engaging speaker. He's really fun to listen to so we're all really excited. We're all med students here so we care about the future of healthcare and we're hoping to see Obama win," Penn Med student Alicia McDonald said.
In the last presidential election, the enthusiasm among young voters seemed contagious as many of them backed then Senator Obama for the White House.
Pollsters and pundits have said the youth vote won't be a major political factor this time.
"It's real easy to get excited about the unknown and it's just knowing what he's done in the past four years, that excites some people, it also deters other," Penn grad student David Gould said.
Pennsylvania is typically a Democratic stronghold for presidential elections but it's the Republicans who believe they can take the keystone state and they brought in their own star power to rally the troops.
This afternoon actor Jon Voight and former New York City Mayor Rudy Giuliani revved up volunteers at a "Get Out the Vote" campaign office in Conshohocken.
"We have a president who has failed us in many ways and that we know is the truth. His record his the truth," Voight said.
"This president doesn't want a second term, he wants a second chance. I'm sorry, you don't get a second chance to put us in risk again; you did enough damage to us. One time. That's it. You're out," Giuliani said.
Giuliani and Voight also made stops in the Scranton-Wilkes Barre area and Bethlehem.
