The voters in this country refuse to take responsibility for their actions and lack of basic comprehension. Because how Democrats are seen as more out of touch than the Republicans, even though Dems hold no political power in either branch of government, is beyond me.
However, the common thread is the same on both sides: privileged White people. On the left, you have the dominantly White Bernie voters stirring the pot constantly, shitting on Clinton without paying any attention to context as to why she lost and what factors led to that happening. They are also throwing a tantrum every time someone who doesn't have Bernie's stamp of approval gains national attention, as the DNC chairman selection proved. These are also the same people disregarding the wants and needs of the minority base of the Democratic Party, and like to tell others that we should give a pass to the racist rhetoric that Trump voters bought into.
Meanwhile, the same base of minority voters (who are probably the only ones in this country who actually have a reason to be jaded about the entire electoral process) are the ones consistently showing up to handle their portion of the electoral bargain, even in low turnout elections. Minority voters have zero problem swallowing their pride and voting for whoever the candidate in the left is.
And yet, we keep running into this issue in three separate countries, in three separate occasions, because the dominant population in those countries are apparently in full self-destruct mode. And that's the worst part of all of this: there is no reason why Trump, Brexit, and possibly Le Pen should be happening at all. But the common thread among them is the same: White people who are either so scared of brown people they accept fascism, or White people who are so privileged, entitled and complacent, that they'll let fascism happen just because they didn't get 100% of everything they wanted.
Until this changes, we are going to keep having these polls show up, and we'll keep wondering why the West seems to be headed towards a path of self-destruction.
TL;DR: Voters, specifically White voters, need to start taking responsibility for us getting to this point and stop blaming Clinton or anyone else for your poor decisions.
