He's the longest-serving Senator from Delaware, and if elected, he'll be the first Catholic Vice President and the first Vice President from Delaware. His father was a car salesman. Biden has two sons, both of which are lawyers. He has a daughter, Ashley, who was arrested for obstructing a police officer back in 2002.
