On today’s “WallBuilders Live” radio broadcast, David Barton declared that Christians cannot vote for any candidate in the GOP primary that will not pledge to nominate Supreme Court justices who will overturn the court’s recent gay marriage ruling.

“If you get a different administration, you can get some different Supreme Court justices,” Barton said. “How many times in the last 30 years has the Supreme Court overturned itself? It did that on nativity scenes, it did that on Ten Commandments monuments, it has done that on homosexuality, it has done that on a number of issues where it reverses itself. So you get some different justices in there and they’ll vote to bring a case back before them on this issue and you may see a complete change as a result.”

After Barton and co-host Rick Green lamented how different things would have been had Robert Bork been confirmed to the Supreme Court instead of Anthony Kennedy, Barton declared that Republican candidates “are lining up now and you need to be asking the question of every one, where are they on the marriage issue and where are they on judges and if you don’t get the right answer, then find a different candidate.”
