Being open source is a very good idea, but it doesn't mean the software that's actually loaded into the machines isn't compromised.
The way to minimize the risk of that is to have two voting machines, with independently developed software in each. Then see if the two produce the same result.
What's important for voting confidence is having the count be auditable, which is much more important than having the machines be secure. After all, banks learned how to do that with money long ago. Banking software has been compromised in the past, but the audit ability catches it.
