[1] After graduating in Medicine at the University of Sassari, Campus began his career teaching in his own alma mater.

He left his seat in the Senate in 2000, once he was elected Mayor of Sassari, supported by the whole Pole for Freedoms.

In June 2009, Campus was elected regional councilor of Sardinia for The People of Freedom (PdL), being the most voted candidate in the city of Sassari.

The new group included, in addition to Diana and Campus, Roberto Capelli (ApI), Claudia Lombardo (ex-PdL), and Massimo Mulas (UPC).

Amid its formation, the group joined the opposition to the regional government led by Ugo Cappellacci (PdL).
