On the heels of the 2011 fight over the limits of public employee unions, Democrats hope to regain seats in the Republican-dominated Legislature that passed the measure.
The issue also is playing a role in one GOP primary. Beavercreek Republican Eric Spicer is seeking to beat state Rep. Jerrod Martin and Greene County Commissioner Rick Perales on March 6 by touting his opposition to the defeated union law.
Newly drawn legislative districts and abortion are factors in other primaries. Fourteen Democratic face-offs and 18 Republican matchups for Ohio House seats are under way. Three Republican primaries are taking place for Ohio Senate seats. Republicans have a big fundraising lead.
