Voters in Ohio went to the polls to decide whether to approve a measure known as Issue 1 that would raise the bar for constitutional amendments on the ballot. In the ultimate irony, the votes against changing the amendment process exceeded the 60% supermajority that the measure was seeking in the first place
How does that result show that they could have succeeded with a 60% supermajority?
At the time of that post, people said it was at 60-70.
