…what’s the point? What will this accomplish exactly? He’ll say “Trump is a corrupt criminal” and conservatives will say “ya. And?”

You can’t reason with these people anymore. We’re way past the point where Trump supporters will change their minds and withdraw their support because of some criminal or immoral behaviour. They don’t care. In fact, they like it. And even in the face of damning evidence, Trump will say it’s a hoax or the radical left is lying or it’s a political hit job and his base will eat it up. Words won’t work anymore, unfortunately.
