Here is just a thought.
The Republicans are using Conspiracy theories, but, they don't care if people actually believe them or not.
Most people do not. Not even the Republicans. The Republicans do not care if they are true or not. They use them for rallying cries.
And even though no one really believes them, it is a way for them to publicly just ignore the true facts, create fear, create chaos, create doubt, create anarchy, use them as distractions, use them to create more hatred towards their political arch rivals.
So they just go along with them, and repeat them, thinking this is their way to own the Democrats by keeping them feeling like their whole political chances are hopeless with so much resistance towards them and reality by the Conspiracy theorists.
It's all strategically planned, calculated, typical for them, easily predictable, and expected. THIS IS WHO THE REPUBLICANS ARE NOW!
It is a Conspiracy Theory led Rebellion, by the most deplorable and dishonest morally inept people in this country, who only care about themselves and the power they can accumulate to force their ways on others.
