Republican presidential candidate Mitt Romney stepped into the middle of the charged battle over organized labor in Ohio on Tuesday, but he avoided weighing in on the contentious legislation that would dramatically limit the collective bargaining rights of public sector unions.
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.
