OCEAN CITY, Md. — Maryland Lt. Gov. Anthony G. Brown (D) touted 70 endorsements of his gubernatorial bid by local officials from across the state at a news conference staged here Tuesday.

The event, scheduled to coincide with an annual conference of the Maryland Municipal League, was intended to build upon the early momentum Brown has claimed in the race to succeed Gov. Martin O’Malley (D) next year.

Brown in May became the first major candidate to enter the race, and this month he named his running mate, Howard County Executive Ken Ulman (D), who joined him at Tuesday’s event.

“Local government is where the rubber meets the road, and I look forward to working very closely with you in the future,” Brown said, as a few dozen of the mayors and other local officials backing his bid stood behind them.

Forty-six of the 70 names on the list released by Brown’s campaign represent cities and towns in Prince George’s County, the jurisdiction where the lieutenant governor lives and one that has an unusually large number of municipalities.

Other regions of the state, including Western Maryland and the Eastern Shore, were represented as well, but not in as great of numbers. The list included seven members of the Baltimore City Council, a city where Brown is trying to make inroads before the June 2014 primary.

Brown was introduced at the event by Kensington Mayor Peter C. Fosselman, who said Brown had “delivered real results, and we need him as our next governor.” In addition to his mayor duties, Fosselman serves as deputy secretary of state in the O’Malley administration.

The summer conference of the Maryland Municipal League is a traditional campaign stop for gubernatorial hopefuls, who typically host receptions and try to ingratiate themselves in other ways with the local officials who attend.

On Tuesday, Del. Heather R. Mizeur (D-Montgomery), who plans to formally announce her gubernatorial bid this summer, tried a different tactic. Mizeur, along with several staff members and supporters, volunteered for a couple of hours at a homeless shelter and emergency food pantry here.

“We’re not wallflowers, we came here to work,” Mizeur said as she got a tour of the 40-bed facility, which accommodates families and individuals.

Two Republican eyeing the governor’s race — Harford County Executive David R. Craig and Blaine R. Young — hosted receptions Monday night for local officials attending the convention. Craig has announced his candidacy, while Young is still weighing a bid.

Attorney General Douglas F. Gansler (D), who plans to formally announce his bid for the Democratic nomination in September, was not making the rounds at this year’s conference.

His campaign, however, announced plans Monday for a series of policy discussions in coming weeks, including one this week on preventing domestic violence.
