Ehrlich and call-in radio show guests Carl Stokes, a Baltimore city councilman, and Jeanne Allen, president of the Center for Education Reform, talked at length about education. Allen is a Republican running for delegate in Montgomery County. She and Ehrlich lamented the "weak" charter school law in Maryland. Expansion has been held back, they said, by teachers unions. On the campaign trail, he has promised to double the number of charter schools.
