How good will electronic voting machines perform if electricity is knocked out by that hurricane?

[Hello]

can you imagine if they were sabotaged by usa enemies who are experts in cyber war!
We don't have voting machines in New Zealand we vote on paper. You have to go to the polling booth and fill in a form and put it in a cardboard voting box manually.
For local government elections we do postal voting. We fill out our forms at home then send them into our local government office by post.
electronic voting machines sounds primitive and like they are vulnerable to fraud and malfunction.
Anything electronic will malfunction at some point in time due to age or not being serviced or maintained.
If you have nuclear power plants and a terrorist decides to take them out on election day then all your machines will malfunction.
Quite a few years back some refugee muslim terrorists tried to blow up an Australian power plant, I think it was during some games or big event and the secret service in Australia got to the terrorists before it could happen; so it is a possibility.
