Say I have my tezos delegated to a baker. There is an open voting period, and that baker votes in my stead. After a little while, I stop delegating. Can I vote again? I imagine the answer is no. But how does the network know that my tezos have voted?
Another scenario is one where, after stopping delegating, I sell my tezos. Can the new owner vote? If not, does this mean that I can buy tezos without voting rights? Seems unfair, specially since there is no way to tell whether the tezos I'm buying have or not voting rights for the current voting period.
