Liberalism and Bureucracy
What keeps liberalism going is Technology - it is the constant flow of sensitive data, information - seamlessly integrating private and public institutions, blurring and deliberately corroding the lines between civilian and military until it all becomes one cohesive organic whole with the Godhead of the Deep State firmly in control. The Deep State is not a conspiratorial cabal of sinister people (although spiritually they may well be) but rather is a critical component central to the longevity of the Liberal State. Electoral politics on its own is far too chaotic and at times messy to guarantee longevity for a political project. The genius of the liberal project is to allow electoral politics to be arena of competing trivial political passions whilst the Deep State in a very Fukuyaman sense continues the reign of History's End.
