You may have seen this before but it's interesting. It's a study of the major factors underlining conservative thought, and states that the major factors are
(i) Death anxiety
(ii) System instability
(iii) Dogmatism, intolerance of ambiguity
(iv) Need for order, structure and closure
(v) Fear of threat and loss
The paper marginally suggests low self-esteem.At the same time, conservatives tend not have openness to experience, and "integrative complexity", defined as " the degree to which thinking and reasoning involve the recognition and integration of multiple perspectives and possibilities and their interrelated contingencies".
Any thoughts?

Political Conservatism as Motivated Social Cognition
Jost et. al
Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism–intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification).
A meta-analysis (88 samples, 12 countries, 22,818 cases) confirms that several psychological variables predict political conservatism: death anxiety (weighted mean r .50); system instability (.47);dogmatism–intolerance of ambiguity (.34); openness to experience (–.32); uncertainty tolerance (–.27); needs for order, structure, and closure (.26); integrative complexity (–.20); fear of threat and loss (.18);and self-esteem (–.09). The core ideology of conservatism stresses resistance to change and justification of inequality and is motivated by needs that vary situationally and dispositionally to manage uncertainty and threat.
