I respectfully disagree.
The Republicans sold Defense down the river twice - in 2011 by approving a $487 Billion cut over ten years (that we are now 2 years into and is causing real reductions), and again by agreeing to allow 17% of the budget (which Defense is) take 50% of the Sequester cuts (even though Defense is Constitutional and Entitlements are not). The Republicans at this point don't care about the military (with the exception of people like McCain, Graham, and McKeon).
Ronald Reagan is rolling over in his grave at what the current crop of Republican leadership are doing to the men and women in uniform of this nation. No group has given as much, and no group has the biggest target on their backs. Military health care, DoD schools, and family support is all going to be cut under the Sequester - not to mention the breaking of faith with hundreds of thousands of loyal, patriotic DoD employees.
So McCain and Graham care about the military. How did they vote on cloture (Hagel)?
