NEW YORK (Reuters) - Republican Dan Senor, a Bush administration foreign policy adviser, said on Wednesday he will not challenge Democratic incumbent Kirsten Gillibrand in the Senate race in New York.
Senor, a former spokesman for the Coalition Provisional Authority that governed Iraq after the March 2003 U.S.-led invasion, is the potential candidate to decide against a run.
Former Tennessee congressman Harold Ford, New York Daily News publisher Mort Zuckerman and New York Congresswoman Carolyn Maloney have all toyed with running for the seat, only to later decide against doing so.
"Over the past few weeks, I took a very serious look at running for the Senate seat in New York," Senor said in a statement. "I ultimately decided this wasn't the right time in my family and business life for me to run."
Senor is a partner at Rosemont Solebury Capital Management and is married to CNN television host Campbell Brown.
Gillibrand was appointed to her U.S. Senate seat last year by New York Governor David Paterson to succeed Hillary Clinton, who became U.S. secretary of state.
No major challenger has emerged to oppose her in a Democratic primary.
According to a Siena Research Institute poll released this week, less than a third of registered New York voters said they would vote for her and another third said they would prefer another candidate. The poll did not ask about Senor.
Republicans Joseph DioGuardi, a former Republican congressman and father of "American Idol" judge Kara DioGuardi, and former Long Island lawmaker Bruce Blakeman are the only other announced candidates.
