CNN's Peter Hamby reports:
The former Massachusetts governor visited an Ohio Republican Party phone bank in the suburbs of Cincinnati, where GOP volunteers were contacting voters about two hot-button measures that will be on the Nov. 8 ballot.
One of them, Issue 2, would overturn Senate Bill 5 –the controversial legislation backed by Republican Gov. John Kasich that curbs collective bargaining rights for public employees.
Another measure, Issue 3, would amend the state constitution to forbid the state and federal government from imposing a mandate to buy health insurance.
Romney expressed generic support for Kasich's efforts to curtail union rights, but he would not say whether he supports or opposes the specific measures.
"I am not speaking about the particular ballot issues," Romney said, only after repeated questions from reporters. "Those are up to the people of Ohio. But I certainly support the efforts of the governor to rein in the scale of government. I am not terribly familiar with the two ballot initiatives. But I am certainly supportive of the Republican Party's efforts here."
