政 combines 正 (correct, straight) and 攵 (action, strike), suggesting the idea of governing by setting things right or enforcing order.
The left side 正 means correct or straight, and the right side 攵 suggests action or authority. Picture a ruler using authority to make things correct and orderly: that is politics and government.
For セイ, imagine a government official saying 'say' the new policy: 'say' -> セイ, as they announce the correct rules.
