During his Reddit "Ask Me Anything":
There was one question everyone on the team wished Obama had answered. [Teddy Goff, head of Obama’s digital team,] probably would have selected it, according to his colleagues, but he didn’t see it at the time.
Would you rather fight 100 duck-sized horses or one horse-sized duck?
In the days following, staffers debated the answer. Most immediately chose the 100 duck-sized horses— they would be easy to stomp on and were, generally, a reflection of the usual day-to-day conflicts in life. A danger to the shins, but possibly manageable. "Ducks are not exactly teeny-tiny—so 100 duck-sized horses (as opposed to duckling-sized horses), while smaller than a miniature pony, are still probably clocking in somewhere around ten pounds each," one Obama official argued. "That’s a lot to kick/throw/battle."
Who would choose to fight a duck the size of a horse? The beak. The wingspan. The ability to defend and attack in the air, on land, and in the water. "Also, lacking a weapon of some kind, how exactly do you defeat it? Wrestling it to the ground seems unlikely. Can you break its legs? Snap a wing?" the official continued. "Yet, it’s just one opponent—you can focus all your energy, attention, and strength on outsmarting it. Maybe it tires easily. Hard to know."
