The article doesn&#x27;t mention one of the most important factors – in the US, Conservatism often comes with a heavy side helping of religion. As a result, highly educated people tend to move away from conservatism even if they may be generally for Conservative policies, because they don&#x27;t want to be associated with people who believe the earth is 5000 years old and that anyone who isn&#x27;t a Christian needs &quot;saving&quot;.<p>The current Republican primaries are showing that this link may be weakening, with Evangelicals no longer being a heavily significant factor in deciding the vote. So maybe the highly educated won&#x27;t be 100% liberal in a decade or two.
