One day after Ken Diamondstone announced he’s running in the 33rd City Council district in Brooklyn, Isaac Abraham, who told the Daily News he would run back in February, announced a Williamsburg press conference to officially launch the campaign.

The advisory says Abraham announce at 1 p.m. on Sunday at Kent Avenue and S. 9th Street.

Abraham owns a hardware store in Williamsburg, and, if elected, would be the first Hasidic Jew to serve on the City Council.

Already running in the race are former Council staffer Evan Thies, Assembly staffer Stephen Levin, Democratic district leader Jo Ann Simon, and environmental activist Ken Baer.

Which is not to say Abraham is without his constituency. “We are proud and honored to support one of our own residents in his candidacy for Council in 2009,” the advisory says.
