The debate over debates is underway in Maryland.

On Friday, Lt. Gov. Anthony G. Brown (D) proposed a series of five debates to his two leading Democratic opponents in the Democrat primary for governor.

Three of the proposed debates would feature the gubernatorial candidates, while their running mates would participate in the other two, Brown said in his letter to Attorney General Douglas F. Gansler (D) and Del. Heather R. Mizeur (D-Montgomery).

“Marylanders are busy,” Brown wrote. “It is important that we agree upon and finalize a public debate schedule soon so they can make plans to see us discuss the issues.”

Mizeur’s campaign manager, Joanna Belanger, said Brown’s proposal fell short of what Mizeur would like to see take place before the June primary.

“Real problems deserve real debates to show Maryland voters which candidate has real solutions,” Belanger said. “Three gubernatorial debates are not sufficient to address all the important issues that affect Maryland’s families. Delegate Mizeur is prepared to debate every week between now and primary election day.”

Gansler spokesman Bob Wheelock declined to comment on the specifics proposed by Brown, but said Gansler and his running mate “welcome a number of robust issue-related debates with Lt. Gov. Brown and Del. Mizeur.”

“We look forward to comparing our record to the record of the lieutenant governor, perhaps starting with the botched health-care rollout and the changes needed to deliver health-care coverage to the people of Maryland,” Wheelock said.
