ANNAPOLIS, Md. (AP) — The Maryland Senate has advanced a new congressional map in a special session on redistricting. Senators could vote later Wednesday on legislation already approved by the House that outlines new boundaries for the state’s eight U.S. House seats. Democrats who have a supermajority in both chambers of the General Assembly control redistricting in the state. They’re moving forward with a map approved on a 4-2 vote by a commission of six legislative leaders that included four Democrats and two Republicans. Democrats say the map makes improvements to the current one, but Republicans say it’s still gerrymandered.
