Ron Paul's support among the police and military

Audacious Epigone has a post up on the disproportionate donations Ron Paul gets from the military and police, relative to other republican candidates.

Here's the comment I left:

This is very interesting data. Based on their ostensible love of liberty and their anti-authoritarian bent, many wouldn't expect libertarians (Paul supporters) to be found disproportionately in rather authoritarian occupations (military and police).

I'm having trouble understanding how the US military personnel being disproportionately right-wing would explain their disproportionate support of Paul relative to other republicans. Right-wing is not the same thing as libertarian and it seems to me that it would be expected that the military would be more right-wing but not necessarily expected that among the military right-wing, there would be disproportionately many libertarians.

The youthfulness of the military would be expected to skew them in favour of Paul but, as Mikey pointed out, that doesn't work very well wrt Paul's disproportionate support among the police.

That the military supports Paul doesn't necessarily lend credence to anti-interventionism. One could suppose that the troops are merely cowardly and/or selfish and that they want to collect their paychecks without having to risk their life, regardless of whether the mission is just or not.

edit added: When I state that troops might support Paul for "selfish reasons", I am of course referring to irrationally selfish reasons, as it would make no sense for a soldier to donate to Paul if he is truly selfish. He would lose some money and his contribution would be too small to affect his likelyhood of dying.
