There is a lot of good data in that link. Some of the most interesting bits:
Around half of early votes are mail-in ballots, which as we saw in the general election, heavily favored democrats
Largest early-voting age-group by far is 66+, which tend to more often lean republican
Voting percentages for Black population is higher than White population by a smidge, though obviously White population has highest voting number overall
Did Not Vote in 2020 General- 24,106
^ This means over 20,000 people who did not vote in the general election are now voting for the runoffs. No way to know which way they lean.
