Spin it how you wish, but in the context of the debate, Obama clearly won that exchange.
How can an "exchange" be clearly won, clearly premised with a failure?
The exchange was clearly won by Obama because he clarified the escense of the matter by telling Romney that to politicize the deaths of four people he was responsible for was offensive....which it is. Your continuation of that politicization is the offense he was refering to.
The facts of the event were made more clear as the two weeks unfolded. There is nothing odd about associating the atttack at Bengazi with the riots all through North Africa immediately previous to that terrorist attack. It took a few days to sort it out. That's just the way things unfold sometimes. To act like Obama was negligent is outrageous.
The bad guys were the terrorists that took advantage of the confusion of the riots to perpetrate their plan. Blaming Obama for this attack is sick. He said he will keep after these terrorists and make them pay. End of story. That is unless YOU support the terrorists because you think it gives you something to blame on Obama.
