Elected at-large, the mayor is limited to two consecutive four-year terms under the city's home rule charter, but can run for the position again after an intervening term. The Mayor is Jim Kenney, who replaced Michael Nutter, who served two terms from 2009 to January 2016. Kenney, as all Philadelphia mayors have been since 1952, is a member of the Democratic Party, which tends to dominate local politics so thoroughly that the Democratic Mayoral primary is often more widely covered than the general election. The legislative branch, the Philadelphia City Council, consists of ten council members representing individual districts and seven members elected at large. Democrats currently hold 14 seats, with Republicans representing two allotted at-large seats for the minority party, as well as the Northeast-based Tenth District. The current council president is Darrell Clarke.
