Surely there must be some provisional ballots and overseas absentee ballots remaining to be counted (”100% of precincts reported” never means that it’s over), and even after those votes are tabulated a recount is likely, but I’d much rather be up by 191 votes than down by 191 votes. Hopefully Kobach can hold on.
You are correct, some counties still need to count provisional ballots and absentee ballots. Johnson County, the largest county in the state and where the delays occurred must do this. There will likely be a recount.
I believe that all of the Kansas counties have abandoned the touch screen machines in favor of paper ballots with an automated tabulation (scanned). So recounts can be manual. Johnson County implemented the new system for the first time for this election.
