Former Greenwood Community Council President and north Seattle resident Mike McGinn announced his campaign for Seattle mayor March 24 at Piecora's Pizza on Capitol Hill.

Today, former Seattle Sonic player James Donaldson also announced his candidacy to challenge incumbent Greg Nickels.

In his announcement, McGinn said his three major issues are the Seattle school system, the city's Internet infrastructure and overcrowded, unreliable public buses.

He said he wants to work with the Seattle Public Schools to improve school performances, and if that doesn't happen, transfer direct control of the district to the city.

"Seattle is one of the smartest and most creative cities in the world," McGinn said on his Web site. "We can do better, and we have to."

McGinn, an attorney and former local chair of the Sierra Club, founded the Seattle Great City Initiative, a group that says it is working to make Seattle a model of economic and environmental sustainability.

At least two others appear to be possible candidates, including former Seattle City Council member Peter Steinbrueck and current editor of The Stranger Dan Savage.
