The gubernatorial campaign of Del. Heather R. Mizeur (D-Montgomery) picked up endorsements Monday from two women’s groups: the Maryland chapter of the National Organization for Women and the national group Feminist Majority.

Mizeur is the only woman at the top of a ticket for governor in Maryland this year. She previously won the backing of Emily’s List, a national organization well known for helping female candidates who favor abortion rights raise money.

Mizeur faces two better-known and better-funded opponents in the June Democratic primary: Attorney General Douglas F. Gansler and Lt. Gov. Anthony G. Brown, who spent Monday tangling over Brown’s role in the state’s troubled rollout of its online health insurance exchange.

“It’s time for Maryland to break the glass ceiling and have a woman as governor, and they could not have a better option than Heather Mizeur,” Terry O’Neill, president of the National Organization for Women, said in a statement Monday.

O’Neill said Mizeur was deserving of the support of the political action committee of Maryland NOW “not just because she is a woman, but because of her vast policy-making experience, her willingness to never settle for the status quo and constant focus on improving communities.”

The other group that announced its support for Mizeur, Feminist Majority, is a national organization that works to empower women economically, socially and politically.

“Maryland has a chance to make history by electing Heather Mizeur,” said the group’s president, Eleanor Smeal.
