If ever:

Wisconsin Attorney General J.B. Van Hollen, who co-chairs John McCain’s campaign in that state, is demanding that election officials use the database to re-verify the identities of voters who registered going back to 2006.

The elections board has refused, citing the database’s error rate. The issue has gone to court, and a ruling is expected next week.

Among the errors with Wisconsin’s database, which has been fully in place just since August, are incorrect ages for 95,000 voters, all of whom are listed as 108 years old. If no birth date was available when names were moved into the electronic system, it automatically assigned Jan. 1, 1900.

In court filings, Van Hollen said “tens of thousands” of ineligible voters could cast ballots, noting that Wisconsin “will be a swing state” whose 10 electoral votes “may be won by a very narrow margin.”
