Seems to go both ways though as I'm not getting any auto completion results for "donald trump stormy daniels" either. I'm guessing they scrub things that are highly sensationalized in the news.
"stormy daniels" doesn't get any autocomplete results for me even without trump, my guess is this is more about adult search terms getting blacklisted rather than political. For example "donald trump e j" gets "donald trump e jean carroll", E Jean Carroll recently accused Trump of a serious sexual assault and this is autocompleting.
