COLUMBUS, Ohio (AP) — Ohio voters have resoundingly rejected a Republican-backed measure that would have made it more difficult to pass abortion protections. The vote sets up a fall campaign that will become the nation’s latest referendum on the issue since the U.S. Supreme Court overturned a nationwide right to abortion last year. The defeat of Issue 1 keeps in place a simple majority threshold for passing future changes to the Ohio Constitution, rather than requiring a 60% supermajority. Ohio Republicans placed the question on the summer ballot in hopes of undercutting a citizen initiative voters will decide in November that seeks to enshrine abortion rights in the constitution. Tussday’s result marks the latest setback for Republicans in a conservative-leaning state.
