Certainly not the libertarians. It'd fly in the face of their almost nonexistent foreign policy. I'd suspect many the tea party folks wouldn't want mercenaries being engaged in situations where we should be deploying our own forces and capabilities. Some see the insane costs of the wars overseas to be because of the amount of resources we spend for outside contractors to do the work the military once did for itself, others are very likely to have no clue of the use of Mercenaries and non government entities at all.
