West Boca Community Council President Sheri Scarborough filed papers today to challenge 21-year school board incumbent Sandra RIchmond next year. One of the Boca civic group’s vice presidents, Frank Barbieri, is already on the school board.

Richmond hasn’t opened a 2010 campaign, but has said she’ll “probably” seek a seventh term. Democratic activist Marcia Andrews is also weighing a run for Richmond’s seat.
