Five years after they joined forces as a presidential ticket, President Barack Obama made a rare joint appearance with Joe Biden at a campaign-style rally that offered a hint of what the vice president’s possible future run for the White House could look like.

The setting was Biden’s hometown, the final stop of Obama’s two-day bus tour, which highlighted the president’s proposals to make college more affordable.

Speaking first, appearing at home behind a lectern adorned with the seal of the president, Biden said the working-class community helped shape his views, such as his “absolute conviction that if you give ordinary folks a fighting chance, they can and do do extraordinary things.”

He then introduced Obama, who said he loved the city because “if it weren’t for Scranton, I wouldn’t have Joe Biden.”

Obama called it a “special day” for him and Biden, noting that it was on Aug. 23, 2008, that he announced Biden as his running mate. That was “the best decision that I ever made politically,” he said.

“Because I love this guy. And he’s got heart. And he cares about people. And he’s willing to fight for what he believes in. And he’s got some Scranton in him,” Obama said.
