From their point of view:

Republican - For God

Democrat - Against God

They have to vote for the party that is for God no matter what.

The other party is going after christ. They see the other side, Democrats, as the anti-christs.

"News" has become "what can you really believe?". It's easy to just not believe any of it but the one issue you care about.

A true Christian would throw their country under the bus if God told them to do it. God comes before Country.
