I would guess that he voted for Obama. Not necessarily because he thinks Obama is a great leader, but because he thinks the tenor and direction of national policy, as implemented by the CIA and other agencies, would be better under Obama than under Romney.
This piece paints a different picture than what I would expect:
Knowing Petraeus' sensitivities to the faux-stimulus of what he has called in Senate testimony "Arab anger," such politicization, or, perhaps better, such Arabizing of the intelligence would likely come naturally to him. No stranger to politicking, Petraeus as CENTCOM commander engaged in what was described as an "unprecedented" political push in early 2010 on behalf of Islam's Israel-centered demonology in order to enhance Americas's military standing in Iraq and Afghanistan. This dovetailed neatly with his perhaps surprising take on Gitmo -- close it, its "existence has been used by the enemy against us" -- and his really shocking take on Hezbollah: "Hezbollah's justifications for existence will become void," Petraeus told the Al Hayat as reported in the Lebanese Daily Star, "if the Palestinian cause is resolved." Given this Arabist sensibility (and don't forget one of his thesis directors at Princeton was Stephen Walt of Walt & Mearsheimer), it's no stretch to imagine the man taking up cry of Islamic video-rage as well.I'd cast Diana West as an opponent of Petraeus, in any event, so take the above with a shaker of salt.

My gut tells me Petraeus is a skunk in the woodpile. Not that the woodpile isn't infested with skunks, like Hillary! and her sidekick Huma; Panetta; and of course Obama.
Thanks for the link.
