A Medford man has taken out the neccessary forms from the secretary of state’s office to run against State Rep. Carl M. Sciortino, D-Somerville. Michael DiBenedetto will now have to gather signatures in Somerville and Medford to appear on the ballot against Sciortino, whose district includes Winter Hill, West Somerville and parts of Medford. Sciortino said his only previous interaction with DiBenedetto was when he and his wife contacted him to express their opposition to gay marriage. Since defeating incumbent Vincent Ciampa in 2004, Sciortino has been a strong supporter of gay marriage. DiBenedetto could not be reached for comment. No other information is available at this time.
