Whether Twitter, Facebook, whatever social media or in-person conversations I've used 'Harris-Biden' or even Kamala-Biden as a variant and I've never once been corrected or challenged on it. This includes Democrats who were very keen to correct me on spelling errors or screech about any kind of typo, grammar, any mistaken date, they will even argue and call me out on 'exact numbers' of something but never even so much as notice I'm saying 'Harris-Biden' or they don't care.

You can try it for yourselves but personally it just astonishes me how long and often I've been doing this and not even the spellchecker nazi types seem to notice lol?
