I’d encourage you strongly to look at the articles about electronic voting on the Princeton Center for Information Technology Policy, especially the 9/27/12 entry about which states could affect the electoral college results if, no make that WHEN, fraud occurs.

See also the 4 part series about NJ that I linked to above about the county computer laptop that committed fraud.
thanks for the links
