Not too long after that, I received in the mail a form I could use to request a ballot, which I didn't use because I already had my ballot. The form, which was partly filled out with my information, came from the Center for Voter Information in St. Paul, but the return envelope was addressed to the Minneapolis Elections & Voter Services (the same address as on the envelope I got along with the other forms in response to my on-line request). I was skeptical about the unsolicited ballot request form but it's legit and not a scam:
The reason Minnesota voters might get a document like this is pretty basic. Under state law, your voter information including your name, your address and how often you vote is public information that can actually be purchased from the state of Minnesota.
Gelms (the Hennepin County Elections Manager) says this particular letter is not a scam and that if the county received this application an absentee ballot would be mailed out.
We will get it, we will process it, we will send you your ballot, Gelms said.
According to a group that tracks nonprofits, the Center for Voter Information is a Washington, D.C.-based nonpartisan, nonprofit organization. It says it sends these out to make it convenient for voters.
