A group of Wisconsin citizens are getting ready to face the state in a Supreme Court case later this year.

One plaintiff, Wendy Sue Johnson came to Merrill to speak to members of Citizen Action, a grassroots political group with more than 42,000 members statewide.

Gerrymandering is creating oddly-shaped districts with the goal of giving one political party an advantage. Wisconsin has already been told by the courts that its districts are unfairly drawn, but many state republican leaders disagree.

"The maps were in place, and while republicans gained seats in '12,'14, and '16 if your argument is that the maps were unfair it should've only happened once. The reason they've won and added seats in the legislature is common sense conservative reforms work," said Governor Scott Walker after learning the case would be taken to the Supreme Court.

When Johnson signed on to the case, she never thought it would end up at the Supreme Court, but gerrymandering is an issue she is passionate about.

"I think that the vast majority of citizens are fed up with how divisive American politics have gotten, and I actually think gerrymandering is at the absolute heart of that," Johnson said.

During her presentation, Johnson showed the difference between an old district map and the current map. When she zoomed in on the neighborhood she lives in, she showed how the lines were altered even at the house level.

Supreme Court Justice Ruth Bader Ginsburg has publicly said this partisan gerrymandering case might be the most important case the court will hear in the upcoming term. The decision will set precedent for the other 49 states.

A three judge court struck down Wisconsin's Legislative Districts last November and ordered new maps to be drawn in time for the 2018 elections.
