The Q phenomenon, if nothing else, has created and sustained a core group of people who believe in and support Trump in a way that never would have happened if Q never existed.
The fact that more and more Q related news stories are coming out demonstrate the "Q-effect" on politics, even if it is only a LARP.
Over and over again Trump criticizes Sessions while Q says to trust Sessions.
When you support Sessions you are not supporting Trump's criticisms of Sessions.
