LIFE IN BLOOMBERG’S NEW YORK: Bronx pol’s secret Facebook page with staffer boytoy.

She’s a real swing voter.

To constituents, she’s Naomi D. Rivera, a mild-mannered, bespectacled Bronx assemblywoman whose social-media page is dotted with her accomplishments, thoughtful sayings and the latest neighborhood news.

But on another, secret Facebook page, she’s Daniela Rivera, a sultry single 47-year-old who shows off her curves, her dance moves and, in one photo accessible to the public, the top of her lacy red bra.

But more than anything, the lawmaker’s Internet alter-ego is devoted to Tommy Torres, a fellow Democrat eight years her junior whom she has been dating for at least two years — and whom she put on her government payroll.

But of course. Plus: “After Post inquiries, she took down the Daniela page. Rivera’s father is former Bronx Democratic Party boss and Assemblyman José Rivera, who in 2008 lost control of the borough machine amid charges of nepotism. Her brother is Joel Rivera, a city councilman.”
