A thousand or more New York City charter school parents are expected to gather in Times Square tonight to urge Barack Obama to send his daughters to charter schools. At the event, they will sign letters to the Obamas making that case. More than 10,000 parents have already signed, according to the groups organizing the event, Democrats for Education Reform and the Black Alliance for Educational Options.

Schools Chancellor Joel Klein is also expected in Times Square, as is BAEO founder Howard Fuller.

The parents have a local message, too: they want the city to open 32 new charter schools by 2010.
