Browser fingerprinting for ballots -- how many bits of entropy on a long ticket?
Not hard if you've got 10 or so multi-way contests or 20 or so ballot measures.

Exactly.
Which is also why the cryptographic voting systems cannot protect voter privacy. Those systems require hash collisions to hide your ballot in the herd of ballots. But the combination of precinct size and complicated ballots means any particular ballot is utterly unique (no hash collision).
I'd be far more charitable towards crypto advocates if they also specified the conditions required for their system to work correctly.

Yup.
Similarly, with postal balloting (vote by mail), your ballot is batched (upon receipt), so will be mixed with ballots from other precincts, therefore more easily tied back to its voter.
