Is "Vision of Liberty" the First Factor of Political Preferences?

Conservatives value above all else what Berlin called the negative vision of liberty, namely, freedom from coercion. Liberals are more willing to balance that against the positive vision of liberty — that is, having a reasonable opportunity to realize one’s potential. The negative vision focuses conservatives on restricting the government’s ability to interfere in people’s lives. The positive vision leads liberals to believe that government has a role in guaranteeing baseline minimums in education, medical care, and healthy communities. Most of us probably accept both visions to some extent, but how we balance the two may be built into our DNA. It is not to be expected, therefore, that a liberal will be converted by reading the great works of conservatism, or vice versa.
