States are checking for double voters… and have successfully prosecuted the offenders.
Rodney Paul Jones, Peter Canova III and Gina Thi Canova are some of the offenders who illegally cast two ballots. Jones cast a mail-in ballot in Arizona for the November 2008 presidential election and also cast a ballot in Colorado where he lived. He pled guilty to a misdemeanor. An Arizona judge last year sentenced him to 50 hours of community service, fined him $4,600 fine and put him on one month unsupervised probation.
As for the Canova couple, they voted in both Arizona and Nevada. Peter Canova III and his wife Gina cast a ballot in the fall 2008 general election, in Maricopa County, Arizona and Douglas County, Nevada. Gina also voted in Arizona's August 2010 primary election and Nevada's June 2010 primary election. Peter’s court-ordered punishment was 200 hours of community service, a $9,200 fine and two years of unsupervised probation. Gina got 300 hours of community service and a $13,800 fine.
The program which cross-checks voting in two or more states has been growing since it started in Kansas. In 2008, Kansas had three cases while Arizona had four. In 2010, Kansas had 11 and Arizona had 9. To read more about the Canovas and Jones in addition to many more cases of vote fraud, visit the RNLA's vote fraud page.
