Marco Rubio said it was a “serious mistake.”

Rand Paul signaled agreement with Justice Anthony Kennedy, asserting the divisive issue should be left to the states.

And Chris Christie slammed the decision as ” incredibly insulting” and ”wrong.”

But one prominent 2016er who remains silent on the Supreme Court’s ruling on the Defense of Marriage Act is Scott Walker.

More than 24 hours after the high court struck down the 1996 law that defined marriage between a man and a woman, the Wisconsin governor had not issued a statement or a comment.

When prompted for an opinion by The RUN, a Walker aide indicated the governor wasn’t about to weigh in.

“Governor Walker is committed first and foremost to continuing his work to turn our state’s economy around and getting people back to work.  We’ve made a good start, but that work isn’t finished, and it is his only priority,” said campaign spokesman Jonathan Wetzel.

During a March appearance on “Meet The Press,” Walker appeared uncomfortable addressing the issue of gay marriage, sidestepping a direct answer on the topic by questioning whether the government should be involved in sanctioning any type of marriages.  The response drew a cursory response from Iowa conservative activist Bob Vander Plaats, who accused the governor of “walking away from marriage.”

Walker later said he still opposed gay marriage.

Other GOP ’16ers who haven’t weighed in on DOMA: Gov. Bobby Jindal and former Florida Gov. Jeb Bush.

Spokespeople for both men did not immediately return an inquiry seeking comment Thursday.
