I cannot find a reliable source containing recent data regarding US military views (military, not civilian elements of DOD) towards specific GOP candidates in the 2012 elections.

I've read Ron Paul has received the most money from American "military" personnel - though journalists have been counting civilians in the DOD as military in their records - but $$$ donation is not an accurate way to enumerate total support. Only ~3,000 US military personal have actually donated to GOP candidates. That's a fraction of the 1.5 million US soldiers and 2.5 million DOD employees potential voters who decided not to donate.

Any serious data that shows what candidates most americans in the military lean towards?
