House Speaker Robert DeLeo and Gov. Deval Patrick behind him with Sen. President Therese Murray stand at the service for former Gov. Paul Cellucci at the state House of Representatives yesterday. Political figures of both parties paid glowing tribute to Cellucci, a Republican who never lost an election in a Democratic-leaning state, in the building where he spent nearly a quarter of a century in public life. Cellucci, 65, died Saturday of complications from ALS, also known as Lou Gehrig's disease.
