Pencils can be erased; but the erasures are obvious. Do you think that all voters are going to complete their ballots without making mistakes? If a pen was used, a whole ballot might have to be redone to avoid ambiguous marks that could be challenged by poll watchers.

All my adult life I've used a felt-tipped pen to vote. It works fine if I mess up my ballot, they give me a new one.
