MADISON (WKOW) -- You may not be registered to vote Tuesday even if you think you are.
Wisconsin election officials say more than 12,000 voters have been made ineligible to cast ballots on Tuesday after two attempts to contact them failed.
The voters could still reregister at the polls on Tuesday.
The Government Accountability Board spent the past year and a half trying to confirm information about more than 777,000 voters who registered between 2006 and 2008.
About 70,000 names were flagged because personal information about them didn't match other databases. The list was subsequently narrowed after two mailings to the 12,431 names which were then inactivated.
Board spokesman Reid Magney says reasons the letters came back included a changed address, a clerical error or a post office mistake. Magney says there is no evidence anyone on the list attempted to vote fraudulently in the September primary.
