U.S. Sen. Benjamin L. Cardin is expected to join the parade of Maryland Democratic elected officials who are backing Lt. Gov. Anthony G. Brown for governor on Monday.
The state's junior senator will reportedly join Brown and running mate, Howard County Executive Ken Ulman at a news conference in Southeast Baltimore.
Cardin is the top Democratic elected official who has yet not stated a preference in the June 24 primary, where Brown faces Attorney General Douglas F. Gansler and Del. Heather R. Mizeur of Montgomery County.
Gov. Martin O'Malley, U.S. Sen. Barbara A. Mikulski, Mayor Stephanie Rawlings-Blake, House Speaker Michael E. Busch, Senate President Thomas V. Mike Miller and four of the state's seven Democratic congressmen previously lined up behind Brown.
Gansler has dismissed the importance of the endorsements, saying they show that Brown is the establishment candidate. Brown has said the support of his fellow elected officials shows his effectiveness at working with people.
Mizeur has amassed fewer endorsements than Brown but has highlighted the support of former Republican U.S. Rep Wayne Gilchrest and Baltimore City Councilwoman Mary Pat Clarke among others. Last week she named one of her early endorsers, the Rev. Delman Coates of Prince George's County, as her running mate.
