Dose Seattle have a strong mayor system?

No, Seattle does not have a strong mayor system. Instead, Seattle has a weak mayor system, in which the mayor shares power with the city council. The mayor is responsible for appointing department heads and overseeing the city's administration, but the city council has the power to approve or reject the mayor's budget and appointments. This division of power can make it difficult for the mayor to implement his or her agenda.

In addition, the mayor of Seattle is not directly elected by the people. Instead, the mayor is elected by the city council, which is made up of nine members. This means that the mayor is not directly accountable to the voters, which can further weaken his or her power.
