You kind of can. Depends how fully auditable you want, but you can have cryptographically anonymized entries, that (I believe?) could even allow the original voter to track their vote, without enabling anyone else to track the vote back to the voter.
It’s a different project, but GNU Taler have some interesting work on anonymized but not forgeable money transactions.

The issue with online voting, no matter what you do, is that someone can force you under threat of violence to vote for a specific candidate, and watch to make sure you do it. Complete privacy in the voting booth is paramount to ensuring that everyone can vote freely.
