Is the identity of each elector who will vote in December available to the public? Or would it be a state by state process to get their identities? (I have sent message to firstname.lastname@example.org - no answer as of yet - their response is below)
Yes, the names of the electors for each state and party are public information. You can find the canonical lists on the websites of the respective state governments. Here the one for California and here the one for Idaho, for example.
There is also an aggregated list on Wikipedia (which is unfortunately missing a few states).
