Change is fine. In fact it's necessary. It's unlikely that Trump will be able to do very much, because the status quo political/economic elites buy power by the metric ton in DC. K Street is about to send more legions in than ever before to ensure that as we speak.
Clinton lost because people are really tired of the same old crap from the establishment, and because the DNC was almost laughably tilting things in her favor in the idiotic primary system. Sanders was getting a LOT of cross-party support, not necessarily because his policies were identical to what people were used to, but because he spoke directly to the nation on the issues of entrenched corruption, income inequality, lack of economic mobility, and the loss of quality jobs in the nation. The big-corporate job export system replaces careers with service industry jobs on the mean.
In the same way, another Bush or generic GOP candidate would have been very vulnerable as well. People are tired of the same crap happening regardless of which dickhead they elect. It's why the Bush and Obama years look so eerily similar : all bought and paid for by the same interests.
Talking heads like to define things oddly, but take the ACA : it was drafted with immense industry support, and it amounts to a massive payoff / fascist corporate handjob at the expense of the US citizenry. You *MUST* buy this corporate product under penalty of law. That's not what Obama was elected to do, if anything that sounds like a Neocon's wet dream : guaranteed profits for the selected corporate sponsors that pay them bags of money through PACs and SuperPACs. All the mainstream Democrat and Republican candidates may as well wear jackets with the various emblems that buy their policy decisions : Goldman Sachs, GE, Walmart, Merck, etc. They sure as shit don't give a wet dookie about any non-donor outside of creating useful idiots.
Clinton lost because she was a terrible candidate and people are finally getting tired of this garbage. Trump won despite being a terrible candidate because he was not identified as an obvious extension of the status quo.
And as for people arguing about 'popular vote'. You cannot make that determination after the fact. Here is why :
When people know their vote doesn't matter, they are massively less inclined to bother with voting. If you want to vote D in Texas, you are wasting your time, so a massive % of people in Texas might have increased the votes for Hillary. At the same time, voters for the obvious winning party in that state are also inclined to stay home, because they feel secure in their choice winning without any real threat. So you have a bunch of groups that stay home for various reasons.
If the EC was removed ahead of time, and the election happened again, you would get a tremendous increase in turnout with much more at stake. Probably at least a 50% increase in turnout. So who knows, with those rules in place and known, maybe HC would have won, maybe she would have lost even worse.
Hopefully we can do better in 2020. I sort of doubt it though. In the meantime I at least hope some positives come from the Trump era, just as I hoped for positives from the previous years under various jackasses of all stripes.
And for the LOVE OF GOD : be nice to each other unless someone is a dick to you first. At that point, either have a real argument or agree to disagree and move on. I've not seen such overreaction and poor class in some time, both from sore losers and sore winners. Grow up (obviously I'm not speaking to most of you here, but you know who I am talking about, it's freaking everywhere right now on social media).
