On April 3, voters will elect three members to the Madison Board of Education. At least two will be newcomers, replacing retiring Ruth Robarts and Shwaw Vang, while board president Johnny Winston Jr. is runing for a second term. Victories by Beth Moss and Marj Passman could give Madison Teachers Inc., the teachers union, greater control of the board’s majority. A victory by Maya Cole, meanwhile, could provide a continued 4-3 split between MTI-endorsed politicians and more reform-minded officials. Here’s a look at the three races.
