Early Voting in Madison

As of yesterday, approximately 26,000 early votes had been cast in the City of Madison. This is out of about 180K registered voters. With three more days of early voting left, and probably 3K more absentee ballots to arrive via the mail, it is entirely possible that 20% of the registered voters in Madison will have voted prior to the 4th.

I'm wondering what turnout percentage will be in Madison this year, as it may chase a record.
