Sen. Ted Cruz scored a big coup in Iowa last month when he won the endorsement of Bob Vander Plaats, the head of the Iowa Religious Right group The Family Leader and an influential Republican power-broker in the state. Vander Plaats has since been crossing the state to campaign for and with Cruz, even engaging in a Twitter spat with Cruz’s main rival, Donald Trump.

Cruz has been attempting to recruit conservative evangelicals to his side by running explicitly on his personal faith and his Christian-nation views, a strategy exactly designed to appeal to a person like Vander Plaats, who earlier this week urged members of his group to convince their fellow churchgoers to caucus in Iowa because the government’s “God-given purposes easily become corrupted without Christians engaged and guiding it.”

In an email to members of The Family Leader on Monday, Vander Plaats lamented that “hundreds of thousands of Iowa Christians stayed home” during the last presidential caucus. To reverse that trend, he asked members to encourage their pastors to distribute a Family Leader-produced bulletin insert on Sunday urging their flocks to participate in Monday’s caucus.

The bulletin insert offers instructions on how to caucus as well as a list of reasons “why it’s important that Christians caucus,” including that it’s necessary to choose “godly candidates” with a “Christian worldview” in order to bring revival to America.

The TFL caucus guide also reminds churchgoers that elected officials are “ministers of God,” and as such, government’s “God-given purposes easily become corrupted without Christians engaged and guiding it.”
