Hennepin County Sheriff Rich Stanek says at least six people are being charged for voter fraud in the 2008 general election.
Stanek said the department investigated 110 allegations of voter fraud his office. In each case, people who were disqualified to vote because of felony convictions were accused of casting ballots.
In some cases the people involved did not know they could not legally vote but, Stanek said, voter fraud is still a serious offense.
"Some elections are decided only by certain votes," he said. "I think as you want the election returns come in even just a week or so away, you're going to see a number of local elections that are won or lost by just a few votes.
"Each vote counts -- that's what we've always told the voters in our state and across this country. Every vote counts."
Three of the suspects charged face two felony counts. Three other suspects each face one felony charge.
