It is pretty clear that Romney's attempts to politicize the killings in Libya have been a disaster. Even Ryan has been more somber and judicial with his remarks. In fact, the stark contrast between Ryan and Romney is very telling.
There are a few corners of the far right that are providing full-throated support for Romney, and there are some Republicans who are trying to be supportive by saying Romney jumped the gun but was right to criticize Obama for his handling of the Middle East in general. While I don't agree with the latter, I totally understand why they are trying to do damage control without fully abandoning their own principles and support for the United States.
However, this is an unmitigated disaster for Romney of his own making. The Intrade market jumped in the last day and now has Obama at a 63% chance of winning. This is a 1.5-2 point jump in the last day, and about an 8-9 point jump in less than a week. That is shockingly bad news if you are a Romney supporter. Even Faux News has Obama up 5 points.
