Story highlights

NEW: Colorado attorney general orders counties to issue same-sex marriage licenses Tuesday

NEW: Gay marriage is now legal in 25 states

Experts believe five other states will soon follow

The momentum is favoring gay advocates, but that could change

CNN  — 

Never has the Supreme Court said so much when saying so little.

When the justices refused to rule on gay marriage cases Monday, it directly cleared the way for the unions to become legal in five states – Indiana, Oklahoma, Utah, Virginia and Wisconsin.

A sixth state, Colorado, began allowing same-sex marriages Tuesday morning, with the state’s high court throwing out the last remaining legal obstacles in the wake of the U.S. Supreme Court’s decision.

And experts believe five other states – North Carolina, South Carolina, Kansas, West Virginia, and Wyoming – will soon follow.
