CHICAGO (AP) — The issue of same-sex marriage has taken center stage in the race for Illinois governor as gay couples statewide are taking their vows.

Democratic Gov. Pat Quinn attended the wedding of a longtime couple at a downtown Chicago museum on Monday and was praised by activists for championing Illinois’ new law allowing same-sex marriage. Those same activists claim that his Republican challenger, Bruce Rauner, has been against efforts legalizing it.

Rauner hasn’t said much about his views on same-sex marriage, aside from that it should have been decided by voters. He told reporters after a Naperville Area Chamber of Commerce event that he has no plans to repeal it unless efforts are driven by voters.

Quinn seeks a second full term. This is Rauner’s first run for public office.
