1. Lena Taylor
Some insiders believe the state senator would enter the race even if Langley seeks re-election. Taylor’s fiery oratory would heat up the campaign, and she brings experience running citywide: In her 2008 bid to unseat then-County Executive Scott Walker, she carried the city, only to lose in the suburbs. To her disadvantage, she’s alienated many of her Democratic colleagues and African-American constituents by siding with majority Republicans to pass concealed-carry legislation, the “castle doctrine” self-defense law, and a reduction of the Milwaukee County Board’s powers.
2. Vincent Bobot
With stints as a municipal judge, assistant city attorney and police lieutenant, Bobot has the broadest law enforcement resume of any potential candidate. As a politician, however, his record is less impressive: He failed to advance in the nonpartisan primary for mayor in 2004 and in the Democratic primary for county sheriff in 2006, when he lost to incumbent David Clarke.
3. Louis Butler Jr.
Appointed by former Gov. Jim Doyle to be the state’s first African-American Supreme Court justice, Butler lost his 2008 race for a full term to conservative challenger Michael Gableman, who relied on big-money attack ads and the business community’s angst over Butler’s pro-consumer rulings in medical malpractice and lead poisoning cases. Later, Republicans in Congress repeatedly blocked President Barack Obama’s attempts to nominate Butler for a federal judgeship in Madison. But the veteran jurist and former public defender could fare better with the Milwaukee voters who elected him to the municipal and circuit court benches (most recently in 2002) and strongly supported him in his 2008 Supreme Court race.
4. Danielle Bergner
The Wisconsin Law Journal and Public Policy Forum have labeled this 37-year-old deputy city attorney a rising star, and she’s impressed her bosses both in private and municipal practice with her ability to negotiate complex deals. Unlike other potential candidates, Bergner has never run for public office and has no political base – a situation similar to Langley’s. He was 38 when he took on (and took down) his boss, then-City Attorney Jim Brennan, after toiling for 13 years as an assistant city attorney.
5. Tony Zielinski
Perhaps the most energetic campaigner in the emerging field, the Bay View alderman and former county supervisor could dip into cash reserves left over from an aborted 2010 race for lieutenant governor. Some observers speculate that if Zielinski runs for city attorney, County Board Chair Marina Dimitrijevic would seek his Common Council seat as a way to escape the impending 2016 pay cut for county supervisors. Zielinski’s downsides lie in his sometimes-volatile temper and lack of courtroom experience.
