However, Greg Heffley's attempts to win the election are primarily focused on gaining popularity. He tries various schemes to improve his social standing, believing that popularity will lead to votes.
Therefore, one implicit condition for running a student council office, as portrayed in the book, could be perceived as:
* Being popular or at least appearing popular. Greg's efforts center around trying to project an image of being cool and likeable, suggesting that popularity plays a significant role in student council elections within the book's fictional universe.
While this isn't explicitly stated as a condition, it's a strong theme throughout Greg's campaign.
