During a sometimes tense meeting Tuesday, Republicans and Democrats on the Wisconsin Elections Commission battled over how absentee ballots from voters should get to clerks. The discussion stems from two complaints alleging clerks in Greenfield and Brookfield broke the law by requiring ballots to be delivered to the clerks’ offices rather than allowing voters to drop them off at their polling place. The clerks also ended drop-off times for absentee ballots before the close of in-person voting on election day.
