If you think the military today is monolithically conservative, keep burying your head in the sand. I can assure you it’s not.
I have been in 23 years and I still find that baffaling that everyone thinks that the military is some conservative bastion. I was especially saddened in 2008 when many military folks voted for Obama especially on the officer side. I know that I will be blasted for even mentioning this but the truth does hurt sometimes.
This is probably due to the 66 percent of military who voted for McCain in 2008 and 64 percent who voted for Bush in 2004. Yes, Obama got 25 percent of the vote, but this was based on knowing nothing about him other than he could speak well when cued by a teleprompter. His policies have not earned him strong approval ratings.
General McChrystal is a liberal. He voted for Obama. General Petraeus is thought to be a RINO.
Then you look at old hands like Weasel Clark. He's anything but a Conservative.
None of these guys believe in absolute victory. Otherwise we still wouldn't be bogged down in Afghanistan right now.
