MADISON, Wis. — It’s not about giving Democratic candidates an advantage at the polls. It’s all about giving constituents a voice on one of the most talked-about issues in the country.

That’s the response of some Wisconsin public officials to the growing number of nonbinding minimum wage referendums popping up in counties and cities all over the state.

But Jennifer Epps-Addison, executive director of Wisconsin Jobs Now, a front group for the Service Employees International Union, told the Huffington Post in a story published Wednesday that her organization and other activists are hoping to use the referendums to entice more liberal voters to the polls in November.
