WILMINGTON, Delaware — For many in the Washington, D.C., area, Delaware is an easy summer getaway to the beach. Some know the First state, more annoyingly, for the tolls required to drive through a few miles of its northeast corner on I-95.

But for Delaware residents, their state, the nation’s second-smallest after Rhode Island, could soon be home to a president, Joe Biden. The two-term vice president under President Barack Obama and 36-year Delaware senator has already given the state outsize recognition through his nearly half-century on the national stage.
