Non US citizens, what's the weirdest thing about USA elections, compared to elections in your country?
For me it is the concept of registering to vote. I am citizen so I have the right to vote automatically and only thing I need to provide is some accepted ID.
If nobody reaches 270 electoral votes, rather than having a second round, the congress decides who wins. FPTP in general. And that most states would give all electoral votes to a candidate with 51% of the vote.
