I think they're trying to show the distinction between the Repub's candidate for President and the Dem's guy... McCain has a distinguished military record (23 years), including a 5 year (+/-) stint as a Prisoner of War, during which he could have been released earlier than some of his fellow P.O.W.'s, but chose not to. This shows a mental toughness that's hard to describe and harder to beat.
Obama military experience is nothing, zip, nada, zero.
While some may not see the importance of a military background,
I personally feel it is imperative that the Commander-in-Chief possess a working knowledge of the military, especially in today's world that is so influenced by terrorists that cannot be reasoned with (i.e.: negotiations/sanctions are not an option). By soliciting the advice of General Petraeus, then dismissing it to pursue his own (dove) agenda, Obama has shown that his ego is bigger then his intelligence level.
The issues you mentioned must be considered, however, if we don't live in a secure nation where we can enjoy those freedoms, they'll mean little/nothing.
