There is winner takes all, yes. But the Duopoly parties are abusing the power of incumbency in a way to stymy, inhibit, suppress, and otherwise make life miserable for Third Party candidates by completely controlling the rules around ballot access, funding, and registration, having Duopoly party Primaries handled by national, taxpayer-funded elections, but all other Primaries or nominations held private, and thus easily marginalized, running "party registry," through public electoral services (itself a dystopian, Orwellian, disturbing system as a backdoor violation to the secret ballot and voter confidentiality that is a bedrock of Democracy in the modern world), and most Third Parties have no recognition on such registry, but are nebulous, "Independents," backdoor deals with media barons lead to vast coverage of the Duopoly, and almost done of anyone else, the FEC and Federal Justices, whose analogous role is Nonpartisan (as they should be) in most First World Nations, are blatantly partisan (to the point of thoroughly compromising the credibility of their position and every action taken within), and strictly DUOPOLY partisan, to boot. Incumbency is indeed abused thoroughly - about as much as United Russia does in Russia and the ZANU-PF does in Zimbabwe - their are just TWO benefitting crooked and power-abusive incumbent parties, and not just one.
Bullets do not cause fire. 
. It's like "the American dream".
