The problem facing the US is the same facing the UK. An archaic old system of two party politics sustained by a first past the post voting system which ensures minority rule, wasted votes, stifles political diversity, power contested in marginal seats and doesn't represent the population. The US and UK (along with Canada) the only western democracies in company with countries like Azerbaijan, Yemen, Liberia etc who practice this archaic form of voting. It needs to be binned. Winner takes all zero sum politics needs to be binned. Alternative forms of voting practiced in modern democracies better represents the populace, governing by a coalition because democracy is too precious to be handed to one party.
