Idea: Using Bitcoin-style Publicly Auditable Ledger for Electronic Voting

Saw this thread pop up on reddit and felt I had to share it to some extent.

So, the idea is not well developed yet at this point in time, but I believe that bitcoin-style encryption could be used for better security in electronic voting machines. Keeping a distributed record of votes cast, maintained in the same manner as the blockchain, would provide nearly unbeatable security against the rigged voting machines that conspiracy theorists/ whistleblowers (justified or not) talk about today.

Admittedly, I am no expert in this topic. So I decided to bring the idea here, just in case it has legs. Anybody have any input?
