COLUMBUS, Ohio (AP) - Ohio voters have overwhelmingly approved a constitutional amendment that will change the way the battleground state draws congressional districts.
    
Issue 1 on state ballots Tuesday had support from both Democrats and Republicans and faced virtually no organized opposition.
    
The proposal was modeled after new map-making rules for Ohio legislative districts that voters strongly supported in 2016.
    
The latest proposal aims to curb gerrymandering, the partisan manipulation of political boundaries that are seen as a cause of partisanship, gridlock, and incivility in Washington.
    
The amendment limits how counties are split into multiple districts and requires more support from the minority party to put a 10-year map in place.
    
If lawmakers can't agree, an existing bipartisan commission will take over. If that fails, the majority party can pass a shorter-term map.
