Appearance of security only wanted
The government will pretend that bad guys are too dumb to have found the security hole so the evil hacker must be punished. The truth is that our voting system is insecure by design. Here in the US there are plenty of instances of vote swapping on electronic vote tallies. Do a Google search if you don't believe me. Don't expect security which prevents deniability by the parities involved in fraud whether they be corporate or government actors. Remember you can't check the code. It is proprietary.
Insist on a verifiable paper printout or paper ballot which can be checked by a human.
