Del. Heather R. Mizeur (D-Montgomery), who is seeking to become Maryland’s first female governor, on Wednesday harshly criticized a plan to help women that was released this week by a leading rival, Lt. Gov. Anthony G. Brown (D).

Mizeur called Brown’s 11-point “Strong Women, Strong Maryland” initiative “lip service” and pointed to policy proposals she has put forward that go much further in the areas of equal pay, family leave and child care.

Mizeur, for example, is calling for the expansion of a child care subsidy program to include 19,000 more slots while the proposal released by Brown on Tuesday includes 1,800 more slots, Mizeur said.

Her campaign released a statement from a representative of the Maryland chapter of the National Organization for Women, a group that has endorsed Mizeur, downplaying the scope of Brown’s proposals.

“Anthony Brown’s plan is little more than political rhetoric designed to pander to women voters, and we deserve better,” Maryland NOW PAC President Sara Wilkinson said. “These ideas would have been revolutionary decades ago. We need concrete plans for change. Not general goals that we have been working on for decades.”

Brown campaign manager Justin Schall declined to comment.

Other aspects of Brown’s plan would create a start-up capital fund for women entrepreneurs, steer more money to breast and cervical cancer diagnosis and treatment and challenge businesses to improve their performance on pay equity.

The June Democratic primary also includes Attorney General Douglas F. Gansler.
