From the Daily News:
Supporters of Bloomberg and Schools Chancellor Joel Klein, including principals from many newly formed public charter schools, have launched a well-financed and sophisticated effort to lobby for more charters and for mayoral control.
In recent weeks, those principals have mobilized parents from their schools for "School Choice" community rallies to demand extra space for new charters in existing public schools, and to pack a series of state Assembly hearings on school governance, the last of which will be held in Brooklyn today.
"You see the organizers and the parents brought in on buses, and the sandwiches distributed, and you can tell it's a highly organized effort," said one official who has attended several of the hearings.
Some disgruntled charter school parents have claimed their principals require them to attend such rallies.
