Re: Anonymous - why?
"So you have to choose which is more important: a FREE vote or a TRUE vote."
Arguably, they are both the same problem. Applying pressure to the voter or modifying the ballot after voting are both ways to tamper with someone's vote, making it neither free nor true, in both cases.
The point is that mitigating ballot fraud, while a significant challenge, is way easier than mitigating voter blackmail in absence of anonymity. Basically, introducing attribution is a cure that's worse than the disease.
Note that I say "mitigating" because you can never completely eliminate election fraud; the process is just too big. That's one of the reasons why it's important for as many people as possible to vote, even when they dislike every candidate. Reduce the statistical impact of fraudolent votes.
