Voting Machines

So apparantly about 18 out of 21 voting machines in NJ can be hacked using hacking software. If these machines were to be hacked, the votes can be altered and affect the outcome of this presidential race. I think NJ needs to double check its machines to make sure everything is fine before this happens. Sequoia, the company that manufactures the machines, say that the machines are approved by the state of NJ and hacking would not occur in a realistic situation. I hope no voting machines in any state malfunction for this election. I really do not want another Florida situation that happened in 2000.
