Re: Not entirely correct.
The popular vote vs electoral college is a red herring. The states elect the president. Each state makes its decision via universal suffrage today, but in the past their electors were appointed or were elected by other means. Each state then casts its votes based on which candidate wins the majority in that state. This system was chosen deliberately, to prevent a small number of populous states from dominating the union.
The USA is not a unitary state, but a confederation of states, each of which appoints its representatives to the federal government by whatever means they choose. The president is elected by the states. Keep that in mind in future and it will all make sense.
