Joe Biden - Biden defeated Republican incumbent J. Caleb Boggs to become the junior U.S. senator from Delaware

Time: 1972

Place: Delaware, U.S.

Details: In 1972, Biden defeated Republican incumbent J. Caleb Boggs to become the junior U.S. senator from Delaware. He was the only Democrat willing to challenge Boggs. His campaign had almost no money, and he was given no chance of winning. Family members managed and staffed the campaign, which relied on meeting voters face-to-face and hand-distributing position papers, an approach made feasible by Delaware's small size.
