Our proportional representation system is not perfect but it can be tweaked to iron out most of its wrinkles. It is inherently fair because each person's party vote counts equally regardless of where they live.
The USA needs to move (with the rest of the civilised world) to a proportional representation voting system. However the probability of this is close to zero, for the same sort of reason they've failed to adopt the metric system - innate conservatism mixed with pig-headedness. There are just too many forces preventing change for the better in the US, as President Obama found out.
