You have to give right wingers a bit of credit. Trump taught them that if you flood the zone with shameless lies of all sorts you can change the narrative. The old saying "we are just asking questions, that's all". Or as Trump liked to say "people are saying". This allows them to just spout lies with impunity. They don't care how crazy or if the ever get debunked. It works on the base. And it works on the media too.
It is difficult to determine if our right wingers are smart enough in that way. It is more likely they are just the gullible believing the lies.
