Former New York City Mayor Ed Koch weighed in on the contested primary in Manhattan’s 14th district Thursday, announcing he’s backing Rep. Carolyn Maloney (D-N.Y.).

“She’s the kind of responsive, independent and tenacious representative New Yorkers need,” Koch said in a letter released by Maloney’s camp. “She has my complete support.”

Maloney, a nine-term incumbent, is embroiled in a primary fight with attorney Reshma Saujani (D). The public backing of the well-known former mayor can’t hurt.

Moreover, it’s noteworthy because Koch is a Democrat but no die-hard partisan. He backed George W. Bush’s reelection in 2004 and is a strong supporter of current Mayor Michael Bloomberg, an independent.
