That's one of the many problems with a Democratic Republic, which is what the US is. It isn't & never has been a democracy. It guarantees a 2 party system with only the political extremes being represented.

That's a clever picture.

I've noticed that since Blair came to power in Britain the two major parties, Conservstive and Labour have been tussling over the middle ground, traditionally the territory of The Liberal or later Liberal Democrat party. This gives rise to extreme right and left parties and independents. As a result this brings a small majority or as in England after the European Referendum and in Australia a hung parliament. This means fringe parties can hold the balance of power. Msy's government creating an absurd alliance with DUP meaning Northern Irish politics could manipulate British policy. Not sure how this correlates with US but certainly puts the brakes on meaningful policy making.
