Romney and Obama each have certain useful characteristics, of course: Romney proved himself to be a master of bureaucracy at the Salt Lake City Olympics; Obama has shown, with the assassination of Osama bin Laden, that he is ready to take lethal action even in the absence of definitive information. Both men, I think it's fair to say, would bring something to the zombie fight.
On the other hand, they might not be able to overcome the highly politicized recriminations that would begin at the outset of a zombie crisis and only intensify as the situation deteriorated. It is safe to assume that, if a Republican were president during a zombie invasion, liberals would blame the crisis on Halliburton and George W. Bush. If a Democrat were in charge, conservatives would blame Obamacare.
We are living in an age in which the velocity of cataclysm seems to be accelerating. Combine that with political dysfunction and widespread cynicism, and you have a formula for eventual disaster, with or without zombies.
