Unlike you, I’m not so sure that McCain would not be an inept CIC. After all, he’s for closing Gitmo and has whined excessively about waterboarding being torture.
I disagree with him on that, but the idea that he's not miles ahead of Obama and Hillary on these issues is a little silly. Obama doesn't even want to listen to terrorist phone calls.
There is no comparison on national security. Making perfect the enemy of good in a time of war is suicidal.
