(CBS) — A November ballot question that will ask voters if they think prescription drug coverage plans should be required to include birth control has been signed by Governor Pat Quinn.

“It is a very important opportunity to the people of Illinois at the ballot box in a language that people understand. Voting on a referendum is a very key way I think to protect women’s health care in our state,” said Quinn.

Although the state already requires insurance providers that cover prescription drugs also cover contraception for women, Democrats argue that in light of the recent Supreme Court decision, the referendum is necessary.

The ballot question will be non-binding. Republicans think the ballot initiative is a scheme to increase Democratic voter turnout.
