Congressional Redistricting

Keith Gaddie has "hung up his spurs."

The election expert from the University of Oklahoma no longer helps state legislatures draw new district lines to maximize their partisan advantage.

He was still wearing those spurs in 2011 when he provided data that helped Wisconsin Republicans enact a legislative redistricting plan aimed at maximizing their power for the foreseeable future.

But now he has reversed course and filed a brief in the U.S. Supreme Court arguing that the practice is undemocratic.

Ohio Senate Democrats say majority Republicans are stymieing bipartisan congressional redistricting talks with "strong-arm tactics."

Ohio Governor John Kasich is joining friend and ex-California Governor Arnold Schwarzenegger's effort to overhaul partisan redistricing that's helped fuel their own Republican party's rise to power.

An Associated Press analysis shows a redistricting process controlled by Ohio Republicans resulted in the party winning nearly two more U.S. House seats and five more Ohio House seats in the last election than would have been expected in neutral circumstances.

Civil rights advocates and Democrats are celebrating after the U.S. Supreme Court ruled Monday that the Republican-controlled North Carolina Legislature had drawn two congressional districts that amount to unconstitutional racial gerrymanders. Election experts say the decision is likely to boost the prospects for success in similar challenges across the South.

The Ohio Attorney General's office has approved the petition summary submitted by the group behind a ballot proposal to change the way the state's congressional districts are drawn.
