As the mayoral race reaches its waning days, the Bloomberg campaign is preparing to announce the endorsement of two senior Brooklyn lawmakers.

Council Members Mike Nelson of Sheepshead Bay and Domenic Recchia of Coney Island, both Democrats, will once again support Michael Bloomberg for re-election, as they did in 2005. The official announcement will come by the end of the week.

Nelson and Recchia both voted for the term limits extension. Recchia was one of the loudest voices in favor of the Council voting for the bill proposed by the administration last fall.

The news comes as the race appears to be tightening, and, according to The Daily News, Council Speaker Christine Quinn, a staunch Bloomberg ally, prepares to endorse Democratic nominee Bill Thompson.

Reached Tuesday, Nelson said he meant no slight toward Thompson.

“I like Billy very much,” he said. “I think he would be a fine mayor. He is a great guy and he is definitely experienced and talented, but I believe in this time of economic crisis that we are in, Bloomberg is the more experienced fiscal watchdog.”

Nelson added that Bloomberg’s record on crime made him a better choice.

“I believe in [Police Commissioner] Ray Kelly, and in this city I never dreamed the crime rate would stay as low as it was when [former Mayor Rudy] Giuliani was here and, to have it actually decrease even as the economy is decreasing—I don’t know if that is appreciated by everybody.”

Recchia declined comment.

Queens Council Member Peter Vallone, Jr. was until now the only current Council member—and one of the few sitting legislators—to announce that he would reach across the aisle to endorse the mayor. Besides Nelson and Recchia, Council members Simcha Felder and Larry Seabrook also endorsed Bloomberg in 2005.

A spokesman for Felder said that he has not endorsed the mayor in this election.

Nelson encouraged his fellow lawmakers should not be troubled by party labels.

“A party is not like your religion or believing in God,” he said. “I always felt you should do what’s best for your community and the city as a whole.”

Bloomberg campaign press aides did not return phone calls seeking comment.
