A review of Milwaukee voting records from the Nov. 2 presidential election has found more than 1,200 ballots cast from invalid addresses in the city, including many cases in which the voter could not be located at all.

The number is a result of a detailed computer analysis by the Journal Sentinel of the city’s voter records and represents about 0.4% of the 277,535 ballots cast in the city in the hard-fought election. Some of the problems may be due to flawed record keeping, such as transposed digits or incorrect street names. Many others, however, cannot easily be explained.

The newspaper’s review, the most extensive analysis done so far of the election, revealed 1,242 votes coming from a total of 1,135 invalid addresses. That is, in some cases more than one person is listed as voting from the address. Of the 1,242 voters with invalid addresses, 75% registered on site on election day, according to city records.

Wisconsin Counties are required by law to send voter address verification cards to new voters. Evidently, this law is not enforced, according to this AP article.

Kevin Kennedy, executive director of the state Elections Board, said local officials have said prosecutors rarely follow up on the undeliverable cards, even though they could lead to charges if voter fraud was involved.
“Municipalities have complained for years the D.A.’s don’t do anything with it,” Kennedy said. “That’s the feedback we get when we hold training sessions.”
In Milwaukee, there have been “several hundred” cards returned as undeliverable, said Lisa Artison, executive director of the Milwaukee Election Commission. The cards are still arriving and have not yet been sent to the district attorney’s office, she said.
In Dane County, District Attorney Brian Blanchard said he didn’t know how many cards had been returned but noted a clerk had bundled up a 6-inch stack.
