Former Delaware Governor and Congressman Mike Castle Passes Away at 86

Mike Castle, a prominent moderate Republican who served as Delaware’s longest-serving congressman and briefly as governor, has died at the age of 86. The Delaware Republican Party confirmed his passing in Greenville, but did not disclose further details.

Castle was renowned for his bipartisan approach and was instrumental in creating the popular State Quarters Program, which honored each state with a special coin, starting with Delaware. This initiative was credited with increasing federal revenue through the coins’ removal from circulation. He also championed similar projects, including coin programs honoring U.S. presidents and national parks, enhancing his reputation as “The Coinage Congressman.”

Throughout his career, Castle was recognized for his centrist views, advocating for fiscal conservatism and moderate social policies. He served 18 years in Congress, supporting measures such as a pay-as-you-go policy for spending and taxes, and contributed to initiatives like child nutrition programs and the No Child Left Behind education reform.

Castle’s political journey also included roles as a state legislator, lieutenant governor, and governor of Delaware in 1985. Despite his success, he suffered an unexpected defeat in a 2010 primary for the U.S. Senate.
