Trump's biggest threat,
Is the truth exposing him. He's always promoted propaganda, remember all his false claims, like The Birther issue which he knew was a lie, Hillary was corrupt yet nothing ever was shown that was true, and he was the one running a scam university, and a foundation he used as a personal piggy bank.
Now it's the election was a fraud, yet he can't provide any evidence, and won't, but he hints and suggests he will. Remember he did this with his birther claims saying his investigators were finding huge amounts of information that would expose President Obama, which he knew were lies.
Why these people backing him refuse to ignore the truth shows two things, they're too lazy to learn the truth, or too stupid to understand it.Eventually these people will realize they're being conned, and getting fed propaganda, and trump's a serial liar , and a career criminal taking advantage of them. They'll become his worse nightmare when they find out he was running a con on them all along. Some of there rioters already have. He lied and people died.
