The ACLU says it's better than the current system, but doesn't believe it goes far enough to prevent gerrymandering, so neither supports nor opposes it.
It's more strongly backed by Dems because we are the ones currently being hurt by the system in place; still, Repubs can see the possability of change in the future (and Ohio still has some moderate Repubs, although you wouldn't know it to see the election ads!)
I voted 'yes'

"Rarely do Republicans and Democrats find an issue on which they can agree in today's divided political climate. Issue 1 represents a rare opportunity for convergence.

On May 8, Ohio voters should approve the measure that seeks to end the partisan process for drawing congressional districts. Instead of allowing the party in power to rejigger districts — often in the most grotesque of ways — passing Issue 1 would seek an equitable way to redraw Congressional district maps. Makes plenty of sense.

Districts would be more compact. You and your neighbor would more likely vote for the same candidate if you live a block from each other. In some places in Ohio, that is not the case.
...

Advocates for the change say it would require minority party input when maps are drawn and "place reasonable limitations that will curtail how a map can be gerrymandered." If a bipartisan agreement cannot be reached, the majority would draw a map that would be binding for four years, not the current 10-year period. It assures other checks and balances as well."

I voted for it. The republican legislature, in 2010 with lots of input from then Speaker Boehner gerrymandered the hell out of Ohio.

I know one of the legislators who worked on it, Vernon Sykes. He is someone I admire and respect.

The solution is not perfect, but will be a VAST improvement over the train wreck we have now.

Vote yes. The issue does have bipartisan support.

Appreciate the info. 'Yes' it is on Tuesday.

Overwhelmingly, with something like 75% of the vote (haven't found complete figures yet, going by this from the Columbus Dispatch)--With 98 percent of the vote counted, Issue 1 was winning with 75 percent of the vote.

The Ohio voters did approve the issue.
