If it was just politics, I'd agree with you. And I hate to be the "but this time it's different" guy, but I really think it is different this time. Trump is more of a religious figure than a politician. His fans literally (in the literal meaning of the word literally) worship him, and he can do no wrong in their eyes. People have made him their entire personality. My wife's church sometimes spends more time talking about Trump than Jesus. In a religious context, personal hardship just strengthens their resolve and convinces them they're being persecuted for Knowing The Truth, just like debunking a conspiracy theory only serves to further convince the conspiracy theorist.

America is getting less and less involved with traditional organized religion, and I honestly think this personality cult is taking a lot of its place.
