There are some things worth losing over. Don’t be involved with this for the politics of it. Be involved only if you believe in something.

 — Joe Biden to Delaware Democrats, March 1996.

It is no small irony that Joseph Robinette Biden Jr was born in the cradle of the New Deal order he would later help dismantle. Neither Biden nor the United States is unique in this respect. Look at just about any developed country’s generous postwar welfare state, and among its rich and powerful foes, you’ll find many who benefited most from its generosity, only to turn against the system that created them, convinced they had done it all on their own.

The Irish heritage Biden would stress throughout his public life was only part of his family history. His parents met in high school: Joe Sr was born to the daughter of a French family with roots in colonial times and a Baltimorian who may or may not have hailed from England; his mother, Jean, to the Scranton son of Irish immigrants and the daughter of a Pennsylvania state senator. “Your father’s not a bad man,” Biden later recalled his Irish aunt telling him. “He’s just English.” Though recounted in jest, Biden’s later approach to various foreign conflicts would suggest he had in fact internalized something from this family lore about the immutability of ancient sectarian grudges.
