The crowd of potential Democratic candidates for Nassau county executive appears to be shrinking.

North Hempstead Town Supervisor Jon Kaiman, long a rumored candidate for the seat, said he is not focused on challenging Republican County Executive Edward Mangano in November.

“I am presently focused on my responsibilities as town supervisor and have not given much thought to a county executive run lately,” Kaiman said in an email on Wednesday.

Kaiman, who is serving his fifth term as supervisor, said in December 2011 that he would “spend the next couple of months looking at whether I want to take it to the next level.”

Several Democratic party insiders have said recently they doubt Kaiman will mount a campaign for county executive.

In September, Newsday reported that Kaiman was the lead candidate to take the chief executive slot at the Long Island Power Authority. But, that appointment is now considered a longshot as Gov. Andrew M. Cuomo has called for abolishing and privatizing the utility after its highly criticized response to superstorm Sandy.

Nassau Democratic Party Chairman Jay Jacobs said last week that he expects to select a county executive nominee by the end of this month.

Jacobs wants former County Executive Thomas Suozzi, who lost to Mangano in 2009, to mount a campaign. Suozzi has said repeatedly that he will not run. District Attorney Kathleen Rice announced last week that she would run for re-election, bypassing a run for county executive.

The remaining potential Democratic candidates include Legis. Dave Denenberg (D-Merrick) and Roslyn School Board member Adam Haber.
