Maryland Lt. Gov. Anthony G. Brown (D) on Monday touted endorsements of his 2014 gubernatorial bid by House Minority Whip Steny H. Hoyer (D-Md.), Senate President Thomas V. Mike Miller Jr. (D-Calvert) and more than 25 other state and local officials from Prince George’s County and Southern Maryland.

The rollout of the new support, at events in Waldorf and Greenbelt, was the latest move by Brown intended to demonstrate his early momentum in a competitive Democratic primary next year in which he faces Attorney General Douglas F. Gansler (D), Del. Heather R. Mizeur (D-Montgomery) and perhaps others.

Word of Hoyer’s backing leaked last week. On Monday, Hoyer, the No. 2 Democrat in the U.S. House of Representatives, said there would be “no on-the-job training necessary” for Brown, who served two terms as a delegate and is in his second term as lieutenant governor. “He’s so extraordinarily ready,” Hoyer said.

Besides Miller, the longest-serving Senate president in Maryland history, Brown backers announced Monday included four state senators and 14 state delegates. The remainder were local officials.

“I can’t imagine anybody more qualified to hold this position,” Miller said of Brown. “I’m so proud to endorse him.”

Gansler, who plans to formally announce his candidacy in September, made a bid for attention Monday as well, previewing a forum he plans to hold Wednesday in Annapolis on “transparency and accountability in state government.”

The event is part of an ongoing “Building Our Best Maryland” tour that Gansler launched last month, and his advisers argued it is consistent with Gansler’s desire to focus more on ideas than making a splash with endorsements.

Among the proposals Gansler will push Monday, they said, is a new requirement that all meetings regarding the development of state regulations that involve state employees and outside parties be made public. Such meetings are currently most often held in private.

Mizeur, who formally announced her gubernatorial bid last week, was also on the campaign trail on Monday, leading a group of volunteers in reading to youth campers in a program in Baltimore. The event was among a string of service projects in recent days that Mizeur said she plans to mix in with more traditional campaign stops.

State senators who endorsed Brown on Monday include Senate Finance Chairman Thomas M. Middleton (D-Charles) and three Democrats from Brown’s home county of Prince George’s: Joanne Benson, Ulysses Currie and Douglas J. J. Peters. Miller’s district also includes part of Prince George’s.

Twelve Democratic delegates from Prince George’s also endorsed Brown: House Economic Committee Chairman Dereck E. Davis, Barbara Frush, Anne Healey, Marvin E. Holmes Jr., Carolyn J.B. Howard, James W. Hubbard, Michael G. Summers, Darren M. Swain, Veronica L.Turner, Kriselda Valderrama, Michael Vaughn and Alonzo T. Washington.

So, too, did Del. Sally Y. Jameson (D-Charles) and Del. John L. Bohanan Jr. (D-St. Mary’s).

Prince George’s Council members Derrick Leon Davis and Ingrid Turner were among the county officials who endorsed Brown. All five commissioners from Charles County did as well.
