The Maryland Senate officially sent the state’s congressional redistricting map to Governor Martin O’Malley for his signature. The Senate took a final vote to correct about 24 typographical errors in the legislation. The House of Delegates passed the bill earlier, a day after the Senate passed the measure. Both chambers already had approved identical maps for the state’s eight districts for the U.S. House of Representatives, but the Senate needed to take the extra vote because of technical errors found in the bill. The districts are being redrawn for the next 10 years in response to the 2010 census.
