Lt. Gov. Anthony G. Brown dominated Maryland’s Democratic primary for governor on Tuesday, but the results were hardly uniform across the state.

Statewide, Brown won 51.29 percent of the vote, followed by Attorney General Douglas F. Gansler, with 24.23 percent, and Del. Heather R. Mizeur (Montgomery), who had 21.71 percent, with 1,982 of 1,988 precincts reporting.

Brown finished on top in 20 of the state’s 24 jurisdictions, including all the big ones, perhaps most notably Montgomery, the home of Gansler and Mizeur. Brown ran second in Cecil, Kent and Queen Anne’s counties, and he was third in Carroll County.

Gansler was the top vote-getter in Carroll, Cecil and Queen Anne’s counties, while Mizeur finished on top in Kent County, where she owns a farm.

Brown’s best performances: Prince George’s, his home county, where he won 76.81 percent; Charles County, with 63.92 percent; and Howard County, the home of his running mate, Ken Ulman, where he won 58.94 percent.

Gansler’s best performances: St. Mary’s County, with 38.72 percent; Carroll, with 36.78 percent; and Queen Anne’s, with 34.18 percent.

Mizeur’s best performances: Kent, with 35.86 percent; Carroll, with 32.52 percent; and Queen Anne’s, with 30.14 percent.
