A few days out, the picture of this race is pretty clear:

1) Biden's lead (52%-43%) larger & more stable than Clinton's in '16
2) Far fewer undecided/third party voters than '16
3) District-level polls (which showed big problems for Clinton in '16) back up national/state polls

If you're looking for a horse race narrative right now, you're not going to find it here. There was a time when it was easy to imagine this race going much differently. Eight days out, it's much, much harder. I've seen...almost enough.

Btw, virtually none of this assessment has anything to do with early turnout data, which tells us next to nothing about the vote preferences of the final electorate.

It's based on a body of polling data that's fundamentally different from 2016's polls.
