Cleveland Mayor Frank Jackson plans to make his re-election candidacy official at 3:30 this afternoon, when he delivers petitions to the Cuyahoga County Board of Elections.

Jackson has more than the 3,000 signatures he needs, a campaign spokesman said. The filing deadline is June 25.

The mayor's bid for a second term came as no surprise when he announced his intentions in April. But his name does not show up on the list (PDF) of those who have pulled petitions for the race.None of those 13 individuals has yet turned in signatures for pre-check, according to the elections board. The field is likely to include announced candidates such as Kimberly F. Brown, Norbert Dennerll, Laverne Jones Gore and Ricky Pittman.

Others who might throw their hats into the ring include former Councilman Bill Patmon and attorney Michael Nelson.
