CNN: Supreme Court's next step on gerrymandering could be its biggest yet

"The justices have struggled to figure out where to draw the line between acceptable partisan influence and an excessive influence that burdens the right to vote," said Danielle Lang of the Campaign Legal Center.

 

"Essentially, the court has not yet settled on a rule to determine the 'how much is too much' question," she said.
 

Lang's group is behind one of the cases making its way to the court. She represents Wisconsin Democratic voters who are challenging district maps. Democrats claim that the maps discriminated against Democratic voters by diminishing the strength of their votes...

 

 

"We proposed a standard that uses political science quantitative measures -- a new standard that has never been presented to the courts before," said Lang. "The court endorsed the use of those measures as evidence of the harmful effects of partisan gerrymandering."
