the cynical people that thought they could lives as islands outside of politics and did not care to engage with anything outside of their interests. this should acknowledge the people that constructed this environment by undermining education, pushing falsehoods, corporatists blocking real change, etc. i suppose you could consider lack of any issue unifying the nation as before with WWII, the Cold War - if it's the end of history and peace/globalization is assured then you can tune out. i.e. it's about the dull invisible work of maintaining standards that keep the system from collapsing and a shared narrative, one people don't feel like exists with all the corruption, nepotism, transgresses from people in power and lack of action on global issues.

The presidential candidates the democrats presented. Trump didn't win this election, democrats lost it by not offering a candidate people wanted to vote for.
