Why Wisconsin Gov. Tony Evers flip-flopped on postponing his state's primary

Why did Gov. Tony Evers, a Wisconsin Democrat, change his mind by trying to postpone the Wisconsin State Supreme Court election this week when both he and Vice President Joe Biden had just recently said that the voting could proceed?

It’s really simple. Republican areas in the state had turned in many more absentee ballots than Democratic areas. This was shocking, because most people had assumed the race between Joe Biden and Bernie Sanders would give Democrats a huge turnout edge. That’s when Evers panicked.
