Liberal vs. Conservative Brains

There have been interesting studies more recently demonstrating that some of the reaction to stimulus we have is brain-based and driven by emotion rather than logic or reason. Further, those studies indicated conservatives have a higher fear or threat awareness system in the brain explaining perhaps why many conservative platforms are more wary of change and stress law and order, a large military, freedom to own guns, closed boarders, etc... How much of our thinking could be based on emotions that are influenced by our biology?
