The City Council has 11 voting members: the mayor and 10 city council members. Two city council members are elected from each of the city's five wards. The mayor and council serve four-year terms. The mayor and one council member from each ward are elected in mid-term election years, and the other five council members are elected in the alternate even-numbered years. The mayor is elected citywide. Approved by City voters in November 2016, and effective with the mayoral election of November 2018, the term of office of mayor will be extended from two years to four years. The mayor is the presiding officer of the City Council and has the power to appoint all Council committee members as well as board and commission members, with the approval of the City Council. The current mayor of Ann Arbor is Christopher Taylor, a Democrat who was elected as mayor in 2014. Day-to-day city operations are managed by a city administrator chosen by the city council. Ann Arbor holds mayoral elections to 4-year terms concurrent with the Gubernatorial election. Until 2017, City Council held annual elections in which half of the seats (one from each ward) were elected to 2-year terms. These elections were staggered, with each ward having one of its seats up for election in odd years and its other seat up for election in even years. Beginning in 2018 the City Council has had staggered elections to 4-year terms in even years. This means that half of the members (one from each ward) are elected in presidential election years, while the other half are elected in mid-term election
