I'm not a crypto fanboy or anything, but I feel like voting is a great application of blockchain technology. It seems like the system could be made to be both anonymous and publicly verifiable, and the vote count would return more or less immediately.

Uh. Blockchain is just a doubly-linked list with hashes. And a set of rules how the peers validate blocks and come to a consensus. Not some magic crypto pixie dust that brings anonymity or prevents fraud.

It could come useful, e.g., for keeping census data to avoid some forms of fraud. E.g. prevent rouge organizers loading elections with "dead souls" voters (Gogol-style). But I don't see any immediate use for election themselves.

Say, the blocks would store anonymized votes (nothing about blockchain itself implements the anonymization). One immediate issue I see is that blockchain only verifies integrity of the blocks after they're in there and out to the public, so it could be verified. Sending them too early would skew election results (observers would be able to see the intermediate results and bias their votes accordingly), and sending them too late would probably make blockchain mostly pointless.
