Will your vote actually count? New voting systems confirm only 58 percent of votes

If you're using one of the newer voting machines, your vote might be tamper-proof but there's no guarantee that it will actually count.

A new study by researchers at Rice University tested three voting machines and found that the systems only confirmed a little over half of all votes cast on them.

It's important that voting be as secure as possible and that systems prevent fraud. Three current systems have proven relatively tamper-proof and even allow users confirmation of their votes: Helios, which is web-based; Pret a Voter, which uses paper forms filled out by voters that are then scanned by a machine; and Santegrity II, a voting system that uses scanning and a special paper bubble ballot.
