politically I think it's more that in America, administrative positions skew heavily towards the political left in or outside Academia. There's a whole theory of analysing American politics based on the idea that the 'professional managerial class' (i.e. salaried administrative types) have interests that are better taken care of by the democratic party and vote accordingly.

I think the cognitive dissonance is more that administrative types want to think of their positions as necessary to the proper functioning of things.
