All you need to do is ask what Republicans like Jim Jordan would say if Biden, Obama, or Clinton were facing the same charges as Trump faces.
In plainer terms, if Trump does/did it, whatever it is is perfectly OK with most Republicans. If others did it, that could be used to defend Trump in the sense of teenagers telling their parents all their friends did the same thing. If no one else did it, well, that's still OK because Trump is just so darned special.
As long as Trump is the best cudgel with which to beat the non-Right, in no small part because Trump causes the most/loudest howls from the non-Right, the Right will excuse anything Trump does. Sadly for everyone outside the Right, their reaction to Trump, understandable as it may be, just makes Trump more powerful among the Right.
I have to add that this includes The Bulwark and me for posting this comment. We work against our own interests in this. Getting rid of Trump requires depriving him of is air time.
