Rep. Donna F. Edwards, a Prince George's County Democrat who became a leading critic of Gov. Martin O'Malley's proposed redistricting plan, acknowledged Wednesday that she had lost her effort to change the map and said she looked forward to representing her new district.

Edwards' office released a statement shortly after the Maryland House of Delegates voted 91-46 to support O'Malley's proposal. The bill will head back to the Senate for technical corrections on Thursday, but the broader political fight is over.

The congresswoman had argued that the proposal harmed minority voters in Montgomery County because it split growing black, Asian and Hispanic populations into congressional districts that are likely to be represented by whites. Edwards' 4th District currently covers many of those communities, but will be pulled out of Montgomery County under the new map.

"The redistricting plan passed in the Maryland House today is not the best approach for minority voters or for all Marylanders," Edwards said in a statement. "Nonetheless, the legislative process in the General Assembly has run its course...Our country and the state of Maryland face pressing challenges that must be matched by thoughtful and authentic leadership from and on behalf of all communities."
