Attorney General Douglas F. Gansler highlights Maryland’s role in  Chesapeake Bay cleanup efforts in a new ad that will begin airing tomorrow in his campaign for governor.

In a second ad, Gansler pledges “to lift up all of our kids” if elected governor by placing new emphasis on teachers’ skill over seniority.

The “Protect our Bay” spot will be broadcast in the Washington market, and the “Every Classroom” commercial will air in Baltimore. Neither spot mentions Gansler’s Democratic primary opponents, Lt. Gov. Anthony G. Brown and Del. Heather R. Mizeur.

In the bay ad, Gansler tells the camera: “As Attorney General, I forced utilities to put in place over $4 billion in pollution controls.”

The ad refers to a 2007 settlement under which American Electric Power agreed to install $4.6 million in pollution-control equipment on 16 coal-burning power plants. The settlement ended a lawsuit brought in 1999 by the U.S. Environmental Protection Agency and later joined by Maryland and seven other states, as well as 13 environmental groups.

Both ads run 30 seconds. 

The primary is June 24.
