Micah Lasher, a protege of Nadler and a newly elected state legislator, filed Thursday with the Federal Elections Commission. Lasher tapped Rob Gottheim, Nadler’s longtime aide, as his campaign treasurer, suggesting that Lasher has Nadler’s blessing. Lasher is Jewish, like Nadler and much of the 12th Congressional District he represents. Lasher previously worked for former New York State Attorney General Eric Schneiderman, New York City Mayor Michael Bloomberg and Gov. Last year, Lasher won with 53% of the vote in a five-person race for an open Assembly seat on Manhattan’s Upper West Side.
