I hear no argument here, just an unsupported statement.
Vote buying is done by having a means of verification of the vote and the voter.
In third-world countries, that involves a carbon copy of the ballot handed over to the paymaster. Intimidation and harassment are also a lot easier when you know whom to target. In a digital world, you are talking nightmare. I am astonished that you can advocate against the secrecy of the ballot. Diane can speak for herself.
