Senate President Steve Sweeney has pushed himself to the top of the potential Democratic field, gaining exposure with a slew of events well outside of his legislative district.

Meanwhile, one of his main rivals is refusing to talk about his interest.

Jersey City Mayor Steve Fulop said addressing any speculation is a lose-lose situation.
