San Diego — Padres owner and chronic wheeler-dealer John Moores, who seems to have inherited the city's Daddy Warbucks role once played by late GOP financier C. Arnholt Smith, may be about to get even richer. The Wall Street Journal reports that DoubleClick, Inc., a software firm Moores owns with San Francisco financier Warren Hellman, erstwhile father-in-law to UC president Bob Dynes, is exploring a sale -- and both Google and Microsoft are said to be interested. Moores, Hellman, and their investment partners paid $1.1 billion for DoubleClick in 2005, reportedly sold off some operations and performed other management surgery, and now want to unload the company for at least $2 billion. ... San Diego Unified school-board member Mitz Lee, who voted with the board majority to buy out the contract of ex-superintendent Alan Bersin, says she's mulling a race next year for the Fifth District city-council seat now held by the termed-out Brian Maienschein. Others said to be lining up for the race include conservative think-tank operator Carl DeMaio. ... All the heavy hitters of Democratic politics, including Barack Obama, Hillary Clinton, and John Edwards, are said to be heading into town the week after next for the state party's convention.
