Maryland Democratic gubernatorial hopeful Anthony G. Brown’s latest television ad highlights his relationship with his adopted son, along with Brown’s practice of promoting adoption and foster care during church visits.

The 30-second spot, airing on Baltimore television stations, is the fourth released by the Brown campaign and builds upon earlier efforts to flesh out the biography of the lieutenant governor in advance of the June primary.

While Brown has advocated policies both as a government official and as a candidate to facilitate adoption and foster care, the ad makes only passing references to those efforts. It instead focuses on Brown’s personal story, showing images of him and 13-year-old Jonathan shooting a basketball in a gym.

“I never knew the impact that adoption could have on a life until Jonathan came into mine,” Brown, a former Prince George’s County delegate, tells viewers.

Brown is also depicted in a church as he describes his efforts “to share the story of Jonathan, the joy he has brought to my life, how amazing a young man he is.” Aides say Brown has made dozens of visits to churches to promote adoption since taking office.

Brown faces Attorney General Douglas F. Gansler and Del. Heather R. Mizeur (Montgomery) in the Democratic primary for governor. Both Brown and Gansler launched their first television ads early last month. Mizeur has yet to take to the airwaves.

On Monday, Brown’s first ads debuted in the more expensive Washington area market. Gansler has already run ads there, as well as in Baltimore.
