Rebecca Kaplan’s entrance into the 2014 mayoral contest means there are now seven candidates who have a chance of winning in November.

The Oakland mayor’s race in 2014 could be the most competitive in recent memory now that Councilmember Rebecca Kaplan has decided to enter the contest. Kaplan’s announcement late last week means there are now seven candidates who have a shot at winning in November: Kaplan, Mayor Jean Quan, Councilmember Libby Schaaf, university professor Joe Tuman, civil rights attorney Dan Siegel, City Auditor Courtney Ruby, and Port Commissioner Bryan Parker.

Kaplan’s entrance into the race also gives both progressives and moderates plenty of choices to be excited about. Kaplan, along with Siegel, should help draw progressives to the polls, while Quan still enjoys the support of organized labor. As for Schaaf, she has crossover appeal among progressives and moderates, while Tuman, Ruby, and Parker promise to generate excitement among centrist voters, as well as among some liberals.

Kaplan, Quan, and Schaaf also appear to realize that they likely will need some combination of support from progressive and moderate voters to win in a city that appears to be nearly evenly divided politically. Kaplan, Quan, and Schaaf, for example, are all advocating to add at least 150 officers to the Oakland Police Department, bringing the total number of officers on the force to at least 800 — and staking out a position that is sure to please moderate, pro-law-and-order centrists. (Siegel is the only top-tier candidate in the race who maintains that OPD can function effectively with about 700 officers; it has about 650 right now.) Kaplan also apparently has mended fences with the Oakland police union, which had strongly opposed her in the past, while Schaaf is pushing for a rainy-day fund that promises to be popular among fiscal conservatives.

Over the past several months, several polls have shown that Kaplan would be a frontrunner in the mayor’s race. It’s also clear that she will be a formidable candidate. But it’s still early, and with so many top-tier candidates in the race, 2014 may produce one of the best mayoral contests we’ve ever seen.
