The 2004 United States Senate election in New York took place on November 2, 2004, along with elections to the United States Senate in other states, as well as the presidential election, elections to the United States House of Representatives, and various state and local elections. Incumbent Senator Chuck Schumer won re-election to a second term with 71.2% of the vote, at the time the highest margin of victory for any statewide candidate in New York's history, and winning every county except Hamilton.
Schumer's vote share would not be surpassed until 2012 when fellow Democrat Kirsten Gillibrand won her first full term with 72% of the vote.
The Conservative Party of New York opposed Republican nominee Assemblyman Howard Mills, due to his support of civil unions and abortion rights.[2] Instead, they supported ophthalmologist Marilyn O'Grady, a failed candidate for New York's 4th congressional district of the 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.
