Why are Republicans so bad at lying?

[The Magistrate]

4. They Are Quite Good At It, Sir

The purpose of their lies is not to convince people something that isn't true is.

Their lies are meant to display cult solidarity, and display their impudent disregard for facts of any sort. Giving assent to a statement false to fact, because it is uttered by a leader of the cult, is how the devotee signals loyalty to the leader and commitment to the cause. The ability to gain such assent from devotees is what establishes a cult leader's rank in its hierarchy. It is what the cult is set to believing on any given day that is always and incontestably true; there is no other standard for the believer.
