Go ahead and doubt if you will...my aunt DID call the Board of Elections about it, and was told that someone DID cast a write-in vote in Grandpa's name (you're right about not "knowing" who he voted for, but that "thank you note" sure gives us a good clue).
Since Hillary was on the ballot, how could it have been a write-in vote for her?

Simple. In NY, if you show up to vote and they don't have your name on the rolls, they simply hand you a write-in ballot. They do not ask for any proof of identity.

You could literally walk into any polling place in the state, tell them, "My name is Mickey Mouse and I'm supposed to vote here," and they are NOT ALLOWED to question you. You will receive a write-in ballot, a pencil, and instructions on how to fill it out. Once you have done so, you can go on your merry way.
