Here in Argentina each party has a big ballot. We can cut it and mix part of different parties, like a president from party A, a governor from party B and a major from party C. But most people are lazy and just select everyone from the same party.

A few years ago, some of the local county majors know that people liked them more than the candidate to governor or president of the same party. So they send helpers to each house to ask people and give them cut ballots with the combination they liked. No judgement. People can choose whoever they want. The county majors know it was better for them in average.

So it's possible to scale it if you distribute the task.

We have in person secret voting. So people can lie and accept the ballots provided by the helpers of the local major and then just pick another when voting. If people can vote remotely, they can be forced to vote under supervision.
