The presidency should be chosen by the popular vote.
Why? What is so magical about the popular vote that it preempts any other way of selecting a leader?
Just because the system ended up electing Trump instead of Clinton doesn't mean the system is wrong. Not even if *you* prefer Clinton.
The Americans have chosen that system for Presidential elections. They have to live with it, or they can change it. It's pointless saying that under some other system someone else would have been elected. And especially pointless to say that because Trump was elected, there's something wrong with the electoral system.
