I fully accept this is an issue where partisan feelings (even if not "Repub" or "Dem" straight up or whatever) effects how you interpret this. Willful act of terror, fixated on "pre planned," "attack period," "is the investigation too slow or is the region chaotic etc...all will effect anyone's view on this.
Personally this attack and what I know on it, doesn't drive me to Mitt's foreign policy over Obama. Then again, everything Mitt has said is either ridiculous or the same as Obama while still somehow bashing him b/c of perceived "tough guy" attitude (which is ridiculous).
If you believe had Mitt been President a few weeks ago he would have saved those people, that's your opinion. I don't believe that.
