The Electoral College – which was first introduced in 1804 – is comprised of 538 electors. Each state’s number of electors is decided by its number of members in Congress, which is dependent on the state’s population. So, when American citizens cast their ballots, they aren’t directly voting for president – they’re voting for electors. This year, Trump took 279, to Clinton’s 228.

The writer of the article was obviously not a math major. 279+228 does NOT equal 538. What happened to the missing 31 electors?

The math is fine. There are states that have not been added to the tally as of yet. Arizona and Michigan are two of them.
