Im thinking a voting machine logs a persons vote on the blockchain?

I think voter fraud has something to do with the "humans" involved.

"Corruption, embezzlement, fraud, these are all characteristics which exist everywhere. It is regrettably the way human nature functions, whether we like it or not... No one has ever eliminated any of that stuff." ~Alan Greenspan

showing the results publicly does not stop who gets to vote.

imagine if a certain demograph did not get the votecoin to be able to vote.
EG the poor who may not have computers to vote.
EG farmers who live out in the countr with no internet access
EG the sick who are too ill to vote

 or someone at the votecoin headquarters sent 10,000 votecoins to 10,000 addresses owned by one person who faked 10,000 addresses/ID's.

what if voters were offered $X for their private key. alot of people on social security benefits would hand over their private key.. take this very forum for example.. lots of people selling forum names for stupid amounts. running scams and not caring about reputation or the ecosystem as a whole. as long as they get a quick payday, they will do anything

in any country maybe 70-80% of the votable population actually vote. so thats 20-30% of the population who dont care about elections that could be bought.

the only thing blockchain can solve is vote tally count fraud, after votes are made. but not the identity fraud or fake ballots before votes are cast.

EG
if there was an election where the population:
25% didnt vote at all
35% voted for A
40% voted for B
(knowing the 35% 40% is 47%, 53% of the votes respectively)
so the blockchain can show that the 47:53 slit is accurate and not counted incorrectly
and B wins

but imagine
16% didnt vote
9% were bought votes that ended up as voting for A
bringing the blockchain public vote count to
44% voted for A
40% voted for B
(knowing the 44% 40% is 52%, 48% of the votes respectively)
so the blockchain can show that the 52:48 slit is accurate and not counted incorrectly

but now A wins. but:
the blockchain cannot prove that votes were bought or not
the blockchain cannot prove why people didnt vote at all
the blockchain cannot prove why voters chose A over B
