Wide-range belief systems centered on political objects constitute ideologies.

Evidence

By and large, our attention will be focused upon belief systems that have relatively wide ranges, and that allow some centrality to political objects, for they can be presumed to have some relevance to political behavior. This focus brings us close to what are broadly called ideologies, and we shall use the term for aesthetic relief where it seems most appropriate. — John T. Jost and Jim Sidanius, Political Psychology, 1855
