Serious idea: Chaumian minted voting system. The poll booth mints tokens* for each item on a ballot, which are pre-encrypted with the voter's public key**, and the voter decrypts and sends anonymously to the proper recipients***.

*multiple option issues have a token for each option, and the intended option gets sent while the the others get discarded. I am sure a write-in system could be achieved somehow, but it would have to be handled differently.

**the key is a one-time use key generated between the booth and the voter, anonymized and free from tracking and thus censorship.

***proper recipients could be a broadcast to multiple or many adversarial parties to keep the system honest
