Having done a bit of a search, I already know that on the first Tuesday after the first Monday of November, voters of the US may cast a vote (using a system specific to their state), which, when tabulated, will (strongly) suggest who some electoral college electors should vote for president.
My question is, what voting systems are used for the "tabulation" in my description above?
This summary from www.usa.gov/election says the "voting system" can vary between states. I understand there can be more than two candidates and (in some states) you can even write in another candidate.
