Campaign
The Conservative Party of New York opposed Republican nominee Assemblyman Howard Mills due to his support of civil unions and abortion rights.  Instead, they supported ophthalmologist Marilyn O'Grady, a failed candidate for the seat representing New York's 4th congressional district United States House of Representatives in 2002.

Perennial candidate Abraham Hirschfeld, then 84 years old, ran for the office on a minor party line; it was the last campaign of his life, and he would die less than a year later.
