There are a large number of technical issues with blockchain voting. The thing about public key cryptography is that it is easy to create a new identity. But in a voting system you need to trust that each voter is a citizen and that they only vote once. This means that public keys of the citizens need to be securely collected by a government authority (for example your local DMV).

Plus we would need culture changes around key management, so that non-tech-literate people can create and protect keys. Which means the people would need some standard for secure hardware to generate keys and sign ballots. Which means we'd need some government standard for "trusted hardware", and that would quickly become an attack vector.

Only after all of that would it be possible for the government to trust votes via public key cryptography. And as Jacob says, the important thing is that the _public_ has trust in the vote, regardless of what government officials believe.
