"The percentage of democrats in the US military is around 40"
How could you possibly get that from that story? The story is about political contributions, not political affiliation, in the military. If only one person in the whole military gave $1 to a democrat, would that make the military 100% democrat? Besides that, the story is three years old. What percentage are giving money to the democrats today after the fine job Obama has done ? What percentage have any money left to give?
