The uniquely American thing about Halfricans is that they identify as black, because society also identifies them as black. As G2 says, Obama was half-white but no one ever talks about that. But that's exactly it: no one talks about the half white part because when anyone sees him, they think black.
I suppose if anyone wanted to split hairs about it, it could be said that Obama looks "blacker" and married a woman identified as black, whereas Kamala Harris looks less "black" and married a man people identify as white. But in the end, Kamala will be identified as black more than Asian, because America is obsessed with blackness and whiteness over anything else, for historical reasons nobody needs to be reminded of.
And the more Trump, Vance, and the surrogates hammer this ultimately pointless point, the more it's going to fire up people who are seen as unambiguously black to rally around Kamala and show up on Election Day. And bonus: because of the racist focus on her in the first place, it's going to also fire up most people of color of all backgrounds to rally around her and vote, too. And bonus bonus: practically no white people who are strongly inclined to vote Democrat anyway are going to peel off from her just because they are reminded of her non-whiteness. If anything, they're going to be extra motivated to make sure they get their vote in, because **** Trump and the Trumpublicans for focusing on this **** in the first place.
And if all this keeps up for the next three-plus months, in the end, that means Kamala is probably going to wipe the floor with Trump, and bring the House and maybe the Senate with her.
I think as of today, things are looking really, really good.
