He asserted privately . . .“about 30%.”
While troubling, I think that's just the odd mathematics of human nature.
Just look at other historical issues:
During the American Revolution, about a third of the population were tories, a third were patriots, and a other third just went along with the guy who was winning at the time to make their lives easier.
The American electorate is similarly divided with 1/3 conservative, 1/3 moonbat, and 1/3 clueless sheep. The military may be a few percentage points better than that in our perspective by virtue of the fact that that the volunteer military by its nature attracts more patriots, but people are still people.
Sounds like the last election....
