David I. Walsh Democratic Henry Cabot Lodge Jr. Republican The 1946 United States Senate election in Massachusetts was held on November 5, 1946.

He was also embroiled in a personal scandal after the owner of a Brooklyn homosexual brothel allegedly frequented by German spies had sworn under oath that Walsh was his client.

He was heavily recruited by the state Republican Party, which sought to counter the supposed popularity of Walsh and Governor Maurice J. Tobin.
