R.T. Rybak's declaration that he isn't a candidate in 2013 already has prompted speculation that the Minneapolis mayor's race could be like none other in the city's history.
For one thing, an expected field of candidates that could be both broad and deep has led some to predict that the DFL convention will deadlock on endorsement, as it has in three of the last five election cycles, including the one in which Rybak triumphed as an unknown.
For another, the city's switch to ranked-choice voting throws a wild card into the process because there's no primary to winnow candidates, and the second and third choices of voters could determine the winner in a large field.
And if the turnout approaches the highly competitive 1993 election, there will be twice as many votes to count -- possibly by hand -- as in the 2009 debut of ranking city candidates. With a hand count, the new mayor's identity might not be known for several weeks.
Already declaring candidacies Thursday were Council Member Betsy Hodges and former Council President Jackie Cherryhomes, out of office since 2001 but still a City Hall player as a lobbyist.
Hodges created a campaign committee on speculation that Rybak might not run; Cherryhomes said she'll do so once she returns from vacation.
Council Member Gary Schiff, who was considering taking on Rybak, said he expects to decide on a run in the first half of January. School board member Hussein Samatar said he'll decide in the next two weeks whether to run. Park Board Commissioner Bob Fine said he's considering a bid.
City Council President Barb Johnson said she isn't running, saying she considers herself more effective in her present role.
