One of the coolest things for me about games that span the day/night barrier is watching more and more cameras activate the automatic flash. I wonder if all those camera flashes are bright enough to have an effect on these shots.
Are you sure the purchase was by the Romney campaign? I suspect there are numerous other parties (like a friend of yours?) that may find it funny or somehow advantageous to redirect vladgyster to that URL.
