City Council Speaker Christine Quinn, 44, may soon be gunning to become New York’s first female mayor. And she appears to have a lot of support from the city’s real estate industry. Indeed, Quinn has amassed more than $3 million in current and leftover funds for a possible run in 2013, with much from usual suspects like Durst, Roth and Rudin. Though their support may make Quinn appear pro-development, she also wins praise from tenants. A former housing activist, she’s cracked down on negligent landlords, while also slamming the generally pro-landlord Rent Guidelines Board. Until this summer, her own office is on the 18th floor of 250 Broadway, where the council is based while City Hall is being refurbished.
