From Ben Smith:

Local elections in New York last night brought a rare result, unseating half a dozen incumbent members of the City Council in a Democratic Primary.
The big winner: The Working Families Party, of which ACORN is a major constituent, which has developed the city’s strongest field operation, which backed three of the insurgent Democrats. Their candidates also had good nights in the citywide races.
….
In any case, while New York authorities say they’re looking into allegations against ACORN, the night’s election results present a complicated fact: Working Families, and ACORN, were running more or less a reform slate, and the candidates who lost were the weakest of the machine standard-bearers.
