The 2006 United States Senate election in Massachusetts was held November 7, 2006. Incumbent Democrat Ted Kennedy won re-election to his eighth full term. This was 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 4th longest-serving Senator in U.S. history, having been there 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 Andy Card also received 3 votes.[2]
Kennedy captured every county in the state, winning at least 62% in each region.[citation needed] 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).
