1972 United States Senate election in Delaware

The 1972 United States Senate election in Delaware was held on November 7, 1972, as part of the broader midterm elections across the country. This election marked a significant political shift in Delaware, as Democratic candidate Joe Biden, a young attorney and political newcomer, defeated incumbent Republican Senator J. Caleb Boggs. Biden's campaign focused on issues such as civil rights, environmental protection, and the need for fresh political leadership at a time of social upheaval in the United States. The victory was notable not only for Biden's age—he was just 29 years old, making him one of the youngest individuals ever elected to the Senate—but also for his subsequent long-term impact on American politics, as he would later serve as Vice President and President.
