The last six months have seen the formation of the Biden Foundation, a way for Joe and Jill to support their pet causes, and the Biden Cancer Initiative to honor Beau. The University of Pennsylvania inaugurated the Penn Biden Center for Diplomacy and Global Engagement to study international issues, and the University of Delaware the Biden Institute for domestic initiatives.

Last — but not least — there’s a new political action committee, American Possibilities, a vehicle for raising money for Democratic candidates.

And maybe for one last try at the White House in 2020…

“Do I regret not being president?” Joe said this spring. “Yes.”
