Total votes is present in the openelections-data-wi repo data, so all we should have to do is make sure that gets into the Mongo data and then output in the raw data.
The write-on column should be possible to fill based on candidate name (which ought to have (Write-In) or (Write In) if the candidate is one).
Marking the winner might be a little trickier, but maybe I can base that off of another state's logic.
