Your history, not mine, and I dispute that public voting in itself was to blame for the abuses which I assume you're referring to.We tried public voting. It lead to some rather horrible abuses.
History man, history ..
Well I live in Cambodia, so yeah, I think politics here are corrupt. As for the US, yes though obviously less so. My point remains: Plenty of people are already open about who they vote for, and I don't see unions targeting them. If anything, making the whole thing more transparent would help prevent the kind of abuse you're talking about. It would make it much easier to see when certain political groups are being discriminated against.The secret ballot enables free and fair elections. Imagine if, for example, a union got hold of how people voted, and then pressured workplaces to fire people who voted for the party they didn't support. You think politics is corrupt now?
