I checked the link Melb posted and found an archetypical description of him:

Quote:


has an angry, almost genetic loathing for privilege, greed, social exploitation, racism, sexism, homophobia, pro-lifers, the religious right, environmental degradation, the NRA, US imperialism, multinational corporations, big business, Republicans in general and George Bush in particular.




Quote:


She ardently believes there is no enormity of which the United States is incapable and regards its entire history as an unbroken legacy of avarice, deceit and injustice.




Finally:

Quote:


...her extremely predictable and tedious attacks eventually exhaust even those inclined to support her.




It would appear that if Cerberus is Centurion, then Melb is Pinko.
