I don't claim this is exclusive to the US, but one thing I don't understand about its politics is why people seem to stop thinking for themselves when called to support abysmal candidates. By all standards Trump and Clinton would be deemed completely unqualified for the presidency (for their own particular reasons) save for the small fact that they have an R and D next to their names. Why is that enough for party supporters to suspend all legitimate criticism? If people are so disenchanted with the two-party system, they should do what people do in other democracies and just vote for another party with better values. The only reason those two parties are still dominant is because the people enable them.
