governor, instead accepting an offer to sit on the powerful Finance Committee and head the Democratic Senatorial Campaign Committee. After Schumer announced he would maintain his Senate seat, another Democrat, Andrew Cuomo, announced his plans to run for Spitzer's vacated Attorney General's seat. Spitzer won an early vote of confidence on January 22, 2005, by gaining the endorsement of the Working Families Party, which has taken advantage of New York's electoral fusion system to act as a kingmaker over Democratic nominees. It is backed heavily by figures from community group ACORN and labor unions, particularly those that broke from the AFL–CIO to form the Change to Win Federation. In the months after the WFP endorsement, several Change to Win unions have announced that they are endorsing Spitzer under their own name, including UNITE HERE, the Teamsters, and the United Food and Commercial Workers. In the latter half of 2005, Spitzer sought to further solidify support for his campaign by touring the state, seeking and giving political endorsements. These included cross endorsements with former-Bronx Borough President Fernando Ferrer in the New York City Mayoral election, Matthew Driscoll in the Syracuse Mayoral election, and State Senator Byron Brown in the Buffalo Mayoral election. The benefit to Spitzer in these endorsement deals was valuable media attention as he stumped for the candidates. As a result of Spitzer's relative speed in uniting state Democrats to his side, he had gained the respect of Democratic leaders nationwide. Bill Richardson dubbed Spitzer the "future of the Democratic Party", at a fundraiser held in June 2005 for Spitzer's gubernatorial campaign. With a large polling lead in the Democratic primary, the June 2006 Quinnipiac University Polling Institute poll showed him leading Nassau county executive Thomas Suozzi 76–13 percent, compared to a 73–13 percent lead in a May 17, 2006 poll. Much of the attention of watchers of New York politics then turned to the state Republican Party, especially the future of three-term governor George Pataki. Polling throughout 2004 and into 2005 consistently showed Spitzer defeating Pataki in theoretical matchups. Such a scenario may have proved unappealing to Pataki. At the time, he was making overtures toward seeking the Republican nomination for the presidency in 2008. Pataki announced on July 27, 2005, that he would not seek re-election and would step down at the end of his term in January 2007. The open-seat nature of the election, along with
