Jun 03, 2010 — Republican conventioneers will end their nominating convention in Manhattan today by considering who'll run against incumbent democratic U.S. Sena. Kirsten Gillibrand. There are three contenders, and a primary is likely. It'll be just the latest disagreement in a series of disoutes at the convention. A skirmish for the gubernatorial nod ended yesterday with former Congressman Rick Lazio's nomination. He overcame a challenge from fellow Long Islander Steve Levy, a conservative Democrat backed by the GOP state chairman, Ed Cox. Martha Foley has more.
