What does the US Military look like? I would venture to say that they are largely conservative in voting patterns...
That said, there are also many who are flaming liberals and don't have a lick of sense. They are just as likely as the average civilian to become disgruntled and want someone to give them their own piece of the pie. I work with a TSgt who is afraid of guns and doesn't see anything wrong with limiting them. Another guy (retired AF) was involved in the DoD civilian unions and thinks unions are the greatest. I bet both of them that in less than 18 months they will have to do some soul searching because Obama (their choice) is at the controls.
If it is still like it was during my 23 years, the military is largely apolitical.
