The Wisconsin Elections Commission has released the final tally of votes, including the write-ins for the declared write-in presidential candidates. The only declared write-in presidential candidate who was on the ballot in at least one state was Peter Sonski, of the American Solidarity Party. He received 561 votes. See the entire tally here.

Wisconsin has easy ballot access for presidential candidates in the general election, and it is rare for any write-in presidential candidate in Wisconsin to get many write-in votes, because all the candidates capable of polling a large number of write-ins are invariably on the ballot. A glaring exception was in 2020, when the Wisconsin Elections Commission kept Howie Hawkins, Green Party nominee, off the ballot because during his petition drive, his vice-presidential nominee had moved her residence, so that her address as listed on the petitions was incorrect. Hawkins got 1,089 write-ins in Wisconsin. That was the largest write-in total for a declared write-in presidential candidate in Wisconsin history. Thanks to Tony Roza for the link.

In 2020 the American Solidarity Party presidential nominee was on the ballot in Wisconsin. In 2016, it had write-in status in Wisconsin for president, and got 284 write-ins.
