Trump - https://www.cjr.org/the_media_today/trump_incoherent_media_sanewashing.php
And you can go from there. Actually, I tried a quite simple experiment:
search = Trump sanewashing
search = Harris sanewashing
There is a message in items returned. Yes, it may be me profiled one way, or the search engine being biased. But, come on -
Try it yourself, use any browser your want, any search engine you want. My bet is your results do not differ from mine. And think for a moment - what is sanewashing, who is doing it, and what if anything may be in it for them.

The bottom line is nobody doubts Harris' sanity. Trump, different matter.

These are not interchangeable human beings. One has a different web presence than the other. Either the whole web is biased, the search engines wrong, or the search engines correct and the phenomenon is as real as night following day.
For a reason.
