Since people seem to have liked the last riddle I posted, here is a new one. It’s based on completely real events surrounding the approaching elections in Russia.

Independent observers and progressive bloggers in Russia are exhorting the voters to bring their own pens to the voting booths. “Please, don’t use the pens that will be provided to you for marking the ballots at the voting polls!” they keep reminding the voters. “During the previous elections, many people forgot to bring their own pens and used the ones that were given to them at the polling stations, and we all know what happened.”

Why do you think it’s so important for Russia’s voters to bring their own pens?
