A large portion of the US population believes the MSM and has a negative image of Trump engraved into their collective mind. It’s like before you were 8 and it never yet occurred to you to question what your parents told you about the world. They don’t see outside the bubble because they don’t know there is anything other than the bubble. Schiffty was playing on that collective inside the bubble mind. Since he was probably involved in the whole “whistleblower” setup I suspect he was fully aware he was lying. However, for some people, lying becomes such an ingrained way of life that they lose the ability to distinguish truth from falsity.
