A 1993 federal law forces about 116,000 voters with unknown addresses to stay on the Kansas voter list. That means almost 7 percent of Kansas voters have addresses where mail cannot be delivered. Kansas has about 1.7 million registered voters.The number of voters with questionable addresses was as high as 174,000 in May 2008, and is down from November 2007 when it was about 154,000. The numbers vary over time and are reduced when lists are purged after federal elections.
There’s a Senate seat at play in Kansas this year, along with the gubernatorial race.
