On the other hand, the USA has contentious elections on a regular basis with basically no violence. That's the real strength of representative democracy.
My guess is that we're headed towards the season finale, but only in a few years. The left already had their moment of huge disappointment (when Obama was elected for "Change", and was not able to actually change anything). Now the right will have the same experience as they far overestimate Trump's ability to follow through on his proposals (e.g. fighting rampant corruption).
