re: Why does the US cling to a two-party system?

I used to think voting 3rd party was "throwing my vote away". I realized in these last primaries that voting republican or democrat was throwing my vote away. That's why I voted 3rd party in November and I won't be voting democrat or republican ever again.

Neither party gives a shite about anyone but the highest bidder lining their pocket. And Trump isn't any better. He just got tired of bribing politicians and decided to cut out the middle man.

When is the last time a politician truly represented their constituents and not special interest groups?
