Sam Yoon, speaking to a group of bloggers tonight, says he would start a formal process to changing the city's current strong-mayor system.
Yoon says city government under the control of a "strong" mayor is not working and that after 100 years of the system, it's time for a more democratically run city.
A charter commission would take 12 to 18 months to recommend changes to the city charter - essentially, its constitution.
Charter reform "is something I'm really excited about," he says. "We haven't had a real debate about our charter since 1909. ... I think it's worth absolutely working on. Does [the current system] really fit way our city is in the 21st century. No other city works like this."
