Major office= (federal) congress, governor, mayor of one of the 15 biggest cities, or winning at least one state in a presidential primary.
Explicitly racist or sexist = explicitly declares it. They have to say something like "yes I'm racist/sexist/believe in discrimination by race/sex" (can be either left or right). Outparty accusations don't count even if convincing (so Trump wouldn't count, nor would a democrat who supports AA but doesn't explicitly declare support for "reverse racism").
Would it count if someone explicitly endorses the "great replacement" theory?

@TimothyJohnson5c16 I think it depends on the details. If they specifically say having a non-white country is bad then yes, but it they just say "mumble mumble cultural changes" maybe not.
@JonathanRay no, it has to be someone who explicitly endorses being racist or sexist (if she's backpedaling she's probably officially denying it, at least).
Does it count if the politician says something like "I have some internalized racism/sexism since I grew up in a racist/sexist society, and I plan to change things so kids don't grow up in that kind of society" type stuff? As in, explicitly declaring to be racist or sexist but also declaring that they don't believe in discrimination by race/sex.
