Sounds like tariq/elon disinformation campaigns may have worked
This is such a weird argument to make when we literally have numbers. The black vote coming out of Atlanta right now is insane. I've heard people argue rural black people tend to vote in person instead of mail, hence why numbers are down there but the big cities have huge gains.
We have numbers from Detroit, the black vote is wild there.
We have numbers from PA, the black vote doesn't look great in Philly but is solid. It's expected to grow on election day. Remember, this isn't 2020: there will be more diverse voting on election day because covid/quarantines aren't keeping people home.
There are crazy high numbers from WI, specifically the cities. Black people are voting.
Dunno about the black vote in NV but I'd imagine the Hispanic vote is way more important there. And for all the handwringing about NV...given that young/new voters are auto registered as independents there, it seems very likely that Kamala is up in the early vote despite republicans having the advantage so far. I feel good about that state.
