From what I remembered from past elections, party ID for early voting generally favored Republicans.
If so, any “evenness” today is bad news.
I do not think Party ID will reach 7 or 8%, but it might reach 5, and 6 is possible.
Unfortunately, that is my recollection as well.
Your memory seems flawed. Here is a report on Florida.

See figure 1. It shows that the independents turn out the heaviest in early voting, followed by the democrats and the GOP pulling up the rear.
Further, it shows the Dems have a much lower ratio of turnout on voting day than early turnout while the GOP stays about the same.
