By the nature of guilt it is likely to happen to any of us. That is exactly why the politicians must be routinely scrutinized and replaced. It is synonymous with "power corrupts;" once the power is enjoined the ego to brandish it prevails, the humility that empathizes with the constituent position once held is gone.
Again this is the deep psychological reason for term limits. There are many contrary arguments but this is the overriding one, the humility or empathy of it all.
It is explicitly opposite the nature of Machiavellianism.
It is also the reason that GWB strayed. By all accounts a good guy, his privileged (elitist) background excluded the strong articulation of conservatism, i.e. individuals of the constituency must assume responsibility for their own decisions and behavior, for freedom to prevail.
