Just because the political circus has left Pennsylvania, the race for the Democratic primary isn't over - and for some students, the hard work is just beginning.
Whether it's traveling across the country as the remaining nine contests are decided or staying in Philadelphia to organize volunteers, several Penn students plan to spend their summers working with a presidential campaign.
College freshman Nate Miller has applied for a job as a field organizer for the Obama campaign.
He will likely hear back from the campaign in a few weeks but doesn't know yet what city he would work in.
"I'd be open to wherever they want to send me," he said. "This is a once-in-a-lifetime experience."
Miller said he thinks college is the perfect time to work for a presidential candidate.
"This is really the only time in my life I can stop everything to work for a political campaign," he said. "And my parents have been really supportive."
College junior Jenna Kalin is also considering a job with the Obama campaign.
She has worked in a field office in her home state of Iowa and says she'd probably continue with similar work in either Philadelphia or back home.
"I was just really excited about Sen. Obama's campaign from the start," Kalin said. "I think he brings something new to politics."
But Obama isn't the only candidate attracting college volunteers. College freshman Patrick Bauer has been involved in the Clinton campaign for more than a year and will continue to work for the campaign this summer.
His previous work for Clinton has included helping coordinate Chelsea Clinton's Pennsylvania events, and he's planning on doing whatever the campaign says it needs this summer.
"I'm pretty sure I'll be deployed after finals over to one of the later states, probably either Montana or South Dakota," Bauer said. Montana and South Dakota hold their primaries June 3.
Since the Democratic nominee could be decided by June and one of the candidates would be out of the race, some of these students' plans may change.
However, they say they aren't fazed by the uncertainty - it's just part of the way campaigns work.
"I'm just going to go one foot in front of the other," Bauer said. "I really can't think months in advance . We'll see what happens and go with it."
For now, the prospect of a historic candidacy - and the hope of seeing their boss win the election - keeps students going.
"I really believe passionately in what this campaign has been about and in Obama as a candidate," Miller said. "It's something I really want to dedicate a lot of time to."
Bauer feels the same about Clinton.
"I don't want to stop until she's in the White House," he said.
