Ohio Gov. John Kasich is joining friend and ex-California Gov. Arnold Schwarzenegger in his effort to overhaul partisan political map-making that's helped fuel their own Republican party's rise to power.
Kasich told The Associated Press Tuesday he's signed a legal brief that opposes the GOP in the momentous Wisconsin-based redistricting case being heard by the U.S. Supreme Court this fall. Other signers include Republicans John McCain and Bob Dole.
The document was filed with the court Tuesday.
At issue is whether Republican lawmakers in Wisconsin drew legislative districts that favored their party and were so out of whack with the state's political breakdown that they violated Democratic voters' constitutional rights.
Both Schwarzenegger and Kasich, a 2016 presidential candidate, have long argued that partisan gerrymandering is contributing to dysfunction in Washington.
