More than 40 people in the meeting room of the Cliffdale Regional Branch library attended a seminar on Tuesday on how lawmakers use election laws to put their interests ahead of the voters. The session covered gerrymandering, or the practice whereby officials design Congressional and state legislative districts with strange shapes – shapes designed to clump together groups of partisan voters in order to keep the opposing political party from winning a majority of the seats. In North Carolina, Congressional districts were designed in 2011 by the Republican-controlled legislature to elect 10 Republicans and three Democrats. They had been split 6-7 in favor of the Democrats. In 2012’s elections, more than half the voters selected Democratic candidates in the revised districts, but nine of the 13 seats were won by Republicans.
