The 2006 United States Senate election in Massachusetts was held November 7, 2006. IncumbentDemocratTed Kennedy won re-election to his ninth (his eighth full) term. This would be Kennedy's last election to the Senate; he died three years later of brain cancer, with which he was diagnosed in 2008. Senator Kennedy was the fourth longest-serving Senator in U.S. history, having served for nearly 47 years.
At the Massachusetts Republican Party Convention[1] Kenneth Chase received the official endorsement with a majority of delegates, though both candidates qualified for the September primary. Former White House Chief-of-Staff Andrew Card also received 3 votes.[2]
Kennedy won every county in the state, winning at least 60% in each county.[8] Kennedy served his ninth, and final, term until his death on August 25, 2009 (here, the completion of John Kennedy's unexpired term is considered to be Ted Kennedy's first term).
