Democratic gubernatorial Heather R. Mizeur is pushing her rivals in the June 24 primary to hold more debates than the three proposed by Lt. Gov. Anthony G. Brown last week.

Mizeur's campaign released on Thursday a letter to Brown, with a copy to Attorney General Douglas F. Gansler, calling for seven face-to-face debates among the three Democrats in the race. Mizeur, a two-term Montgomery County delegate proposed all of the debates be carried on television, radio or streaming online. She suggested that each debate focus on a specific issue area.

"Without a robust conversation about all the major challenges facing our state, it will be difficult for voters to make informed decisions on Election Day," she wrote.

A spokesman for Brown's campaign could not be reached immediately to comment. The lieutenant governor suggested Friday that five debates -- three for the top-of-ticket candidates and two for their running mates -- be held in regions around the state.

Bob Wheelock, a spokesman for Gansler, said his campaign is formulating its own proposal but would like to see more debates than Brown proposed.

Mizeur neither rejected nor accepted the idea of two lieutenant governor debates, saying the priority should be to resolve the details of gubernatorial face-offs.

Brown is running with Howard County Executive Ken Ulman. Gansler's running mate is Del. Jolene Ivey of Prince George's County. Mizeur chose the Rev. Delman Coates, pastor of a large church in Prince George's County.
