DENVER — Gay rights groups promise that same sex marriage is coming to Colorado, either through the courts or the ballot box.

They pledged at a rally Monday to pursue a ballot measure in 2016 to legalize gay marriage unless courts strike down Colorado's ban on the practice first. Two lawsuits are making their way through state court to do just that.

Judges have struck down gay marriage bans in several conservative states recently. The appeals of those rulings will be heard in a federal court in Denver.

But gay marriage supporters say if they lose in court they will go to the ballot box to overturn the gay marriage ban Colorado voters passed in 2006.
