The story is here. 

“On Sept. 9, Irving Anders obtained and filled out an absentee ballot from Prairie du Chien Township in Crawford County; four days later on Sept. 13, he obtained and filled out an absentee ballot from Millville Township in Grant County.” 

I don’t know if he was registered twice in the state or whether he was a same day registrant.  Either way, it isn’t good.  If the former, it shows registration fraud breeds voter fraud.  If the latter, another reason to question same day registration.
