Bob Vander Plaats, the head of the social conservative group The Family Leader, will reportedly be deciding in the next few weeks whether to run for the U.S. Senate seat being vacated by Democrat Tom Harkin this year. While he hasn’t made a final decision yet, Vander Plaats is widely considered to be the frontrunner for the Republican nomination if he enters the race, and already seems to be selling himself as a candidate.

Progress Iowa shares a video of Vander Plaats speaking at The Family Leader’s annual “Life, Marriage & Family” rally yesterday, in which Vander Plaats lays out his Christian nationalist view of government. Speaking about recent court decisions in favor of marriage equality, Vander Plaats – who led the effort to oust three Iowa Supreme Court Justices who ruled for marriage equality in 2009 – claimed that “rogue justices” and President Obama (“who is in over his head”) have “forgotten” that the American government is actually an instrument of God.

“God institution (sic) government,” he said. “He has three institutions: He has the Church, he has the family, and he has government.” He went on to explain that “the purpose of government: to promote righteousness,” which he counts as following “God’s principles and precepts” on everything from economics to family policy to foreign affairs.

Vander Plaats frequently portrays the Constitution as an extension of the Bible, claiming that marriage equality is unconstitutional because it “goes against the law of nature’s God” and that the Supreme Court’s DOMA decision provoked a “constitutional crisis” by “going against the document that predates the Constitution.”

The remarks start about three minutes into the video.
