George Pataki opted not to seek re-election. Pataki did not run again, but Cox later chose instead to seek the seat held by incumbent U.S. Senator Hillary Clinton (D) in the 2006 New York U.S. Senate election. However, after Pataki endorsed a rival Republican--Westchester County District Attorney Jeanine Pirro—for Senate, Cox announced on October 14, 2005 that he was no longer running. In 2007 and 2008, Cox chaired John McCain's presidential campaign efforts in the State of New York. New York Republican Party Chairman (2009–2019) Cox was elected chairman of the New York State Republican Committee at the committee's meeting on September 30, 2009. Cox had a seven-point "agenda for the future" when elected chairman: to be "a full-time chairman"; to win election victories in the 2009 local elections; to re-build the state party's staff; to "re-establish credibility" of the state party nationally; to raise money; to recruit a "slate of candidates up and down the ballot"; and to win statewide elections in 2010. Cox announced on May 20, 2019 that he was joining President Donald Trump's re-election campaign and that he would not run for re-election as Chairman of the New York Republican State Committee stating, "Serving as Chairman of the NYGOP over the last ten years has been one of the most rewarding chapters of my life, and I will continue to actively help elect more Republicans here in New York'". On July 1, 2019, Nick Langworthy, the Erie County Chairman succeeded Ed Cox as Chairman the New York State Republican Committee.
