OPINION  In America all voters must have fair and equal representation. Gerrymandering prevents that. The political party that controls the state government is able to draw the maps every 10 years. Wisconsin Republicans in 2011 used political consultants armed with high-tech software to tinker with district lines to ensure the GOP will virtually always win 59 of the 99 Assembly seats, even in an election where Democrats over-perform. That’s completely un-American.
