"Voting Machines" come in 3 types:
1. DRE where your vote is Directly Recorded Electronically.
2. Ballot counters where your vote is recorded on a paper ballot and the machine is fed them, counts them and spits back out the ballot to be saved.
3. Ballot markers that mark a paper ballot and you then send it through a ballot counter.
1. There are only 6 US states where DRE machines are used at all, only Lousiana uses them for all districts. All 6 of those states want to get rid of the DRE machines and switch to paper ballots and Ballot Counters. Trump could easily hack Louisiana ... but does not have to. They already have that state. The other states where some counties use DRE are New Jersey, Ohio, Indiana, Tennessee and Utah. They use them in certain older counties. Tennessee, Utah and Indiana are not in play. New Jersey is a lock for the Democrats. Ohio is the only 'swing' states where hacking could give Trump an advantage.
2. Ballot counters can be easily checked to see if they are hacked. Just hand count 1000 ballots and feed them to the machine. No one is going to bother hacking them.
3. Ballot Marking Devices are typically used by people with vision issues. If you do not have vision issues you can ask to use the BMD and visually check to see if it marked the paper ballot correctly. No one is going to hack them.
It is reasonable to be very concerned about the state of Ohio being hacked. But if the Democrats win Ohio, they will win the US senate even without Ohio.
