I can’t speak for the people with the power to actually make this policy, but for the people I know who have been big believers in this, it’s because this is the part of the Bible they actually like: Jesus coming down from Heaven with sword in hand to destroy all the wrongdoers (read: people the believers don’t like). They have absolutely massive amounts of Christian fanfiction devoted to how they want all this to go down (see: The Left Behind series). This is their superhero power fantasy type beliefs.

Take some queues from Van Hollen and use the power they’ve assembled to get themselves elected, and mobilize themselves and their voters to address the problems directly instead of making large shows of asking Republicans to do the right thing.
