Issue 1 amends the Ohio Constitution by putting rules in place, where none exist now, aimed at creating districts that make geographic sense - rather than districts designed solely with political gain in mind.
How often - and to what extent - counties can be split will be severely limited. And a new 10-year map cannot be enacted without significant buy-in from both major political parties.
The unofficial vote tally showed Issue 1 with a 75 percent to 25 percent lead -- 1,165,409 votes for to 391,527 against. The official vote will be known within a few weeks.
