Impeach Obama On Benghazi?

It appears that even John McCain is now backing down, if without apologizing.

I pretty much expected this to go away after the election after I talked to a retired military officer with a lot of contacts in the upper brass who said “believe Powell, not McCain.” I pretty much stopped being interested in it at that point, and figured it would not survive the election one way or the other. Looks like I was right. Unless someone’s got a strong reason for me to believe this Benghazi thing really should have legs still? Something other than muttering?
