Answer:
Electors don't ACTUALLY have to vote. It go by the Majority, so if Majority people votes Democrats then democrats gets the ENTIRE electoral college votes, and the other way around. But the electoral college vote from your state depends on your member of House of Representatives and Senators, in another word winner take all. This is why you should always vote and do the census, because doing the census determines how many electors you will have, the more the better, and voting would be a good idea too.
