As of right now, California is reporting about 72% of the expected total, at about 12 million votes. If the ratio is maintained, we can expect about 2.8 million more votes for Harris from California alone. And Trump can expect another 1.8 million from California.
There are a couple hundred thousand votes to count in each of Oregon, Maryland, and DC.
As of 10:30am ET on November 11, populous states that have counted less than 95% of the expected votes include:
Just eyeballing those, and a few other smaller states with a significant number left to count, it looks like we can probably expect a few million more Harris votes to be added, and maybe another million or two Trump votes to be added.
So a quick eyeball estimate is that the 2020 minus 2024 gap should probably shrink by about half when it's all counted.
