I don’t think there has ever been a better adjective/noun team than staunch & asshole.  The only superior 1-2 punch would be the yellow turtle neck/leather jacket combo worn by Terry Silver while dropping off John Kreese at the airport.  But then again, that’s like comparing apples and platinum bars.  I’m tired of staunch being wasted on nouns like Republican.  The definition of staunch asshole would be as follows:

Stanch Asshole – someone who is firm or steadfast in principle, adherence, and loyalty to being an asshole.
