Cut off the flow of all information detrimental to him and his puppetmaster Putin. It's the only way.
His base will never need convincing. It's the other who have to stop hearing about his humiliation and dedication to the Putin strong man. Plus all his toady sycophant Republican pols have to stop hearing this stuff. They are aren't as stupid as the look, act, sound. They know anything that comes out against their dementia don looks bad for them. So shut up stifle it stop it.
Don'tcha think?
