Whirmeldae Wilson is one of several Berkeley voters who have complained about Hoskins in recent elections, according to Election Board documents.

Wilson told authorities Hoskins first stopped by her house in 2012 to lobby for her vote and to inquire if she wanted to vote absentee. She said Hoskins collected the application she had filled out, then later came back and offered to mail her completed ballot.

To ensure no one could tamper with the ballot, Wilson said, she sealed each side of the envelope containing her absentee ballot with packing tape.

In that race, Hoskins defeated his opponent, Babatunde Deinbo, 517 votes to 418. Thirty-six percent of Hoskins’ votes came from absentee ballots — the highest share received by any of the 32 mayoral candidates in St. Louis County that election cycle. The next highest share of absentees among mayoral candidates was 14 percent. Countywide, 8.6 percent of votes came from absentee ballots.

In April of this year, when Hoskins was on the ballot again, Hoskins paid Wilson another visit, she reported to authorities. He told her someone from his campaign would drop off an application to vote absentee. A campaign worker later stopped by with an application, she said. Wilson said she was told that she didn’t need to fill out the whole form, but just had to sign her name.
