Brimley's mayoral campaign contributions only from residents and former residents of Weston.

Why this is right
Since the Residents law of the Contributions → or land are the Former Residents rules that restrict one’s ~$100 actions, if or the law is Residents → ~Registered not or applicable, Former Residents no action ∴ Contributions → ~Registered is required. And since the law of the land regarding contributions is the only law regarding contributions, no other laws could apply. Since Brimley’s campaign only accepted contributions from residents and former residents, no requirement to register contributions applies to Brimley’s campaign.
