Re: Donald Trump - POTUS
Trump is the duly elected president as per the rules (electoral college votes) but Hillary Clinton won the popular vote by almost 2 million votes (cf. Al Gore)
Victory in one or two swing states (Ohio, Pennsylvania, Florida, Illinois) would have been enough to win her the presidency.
Personally i believe that the electoral college system is flawed. In all but two states the winner takes all of the State’s Electoral votes (even if you win by the narrowest of margins say 50.5-49.5%; so 49.5% of people have no say!)
I think it should be %age votes x total number of seats in a state = Electoral college votes
