The crazy thing is, @JonRowe and @ravenight are both right. Two different ways of objectively looking at the exact same situation. Forget about the alt-right bastards, forget about EMAILS, a large portion of the people who supported and voted Trump did so because they felt (correct or not) that their personal situation was not improving or getting worse over the past decade, and Trump made a very loud and direct promise to address that exact issue. From the rural farmer, to the small-town factory worker to the suburban sales/middle management person, to the inner city restaurant worker and everyone in between, this is the most important issue. How do I fit in? How do I support myself and my family? How do I succeed? When you feel like none of those things are happening, you need someone to blame, and that someone was "the government".
None of what is happening right now (Dodd-Frank, Betsy DeVos, Immigration Ban, Sean Spicer and Kellyann Conway lying, Steve Bannon on the NSC) means shit to these people. The only way they wake up and understand that Trump lied and that the GOP is screwing them far harder than the previous administration is when it's already done. It will take 4 years of decreased prosperity, 4 years of these people actually losing ground instead of gaining it, before they will understand that they've been had. Everything else is noise to them.
If the opposition was smart and organized, they would be running campaigns right now based on educating these people about the one issue that matters most to them, their own prosperity. Forget about attacking Trump on immigration, forget about harping on how unprofessional and ill-equipped he is to handle the political aspect of POTUS, forget about his ethical conflicts of interest, those are all things that only reach people who are already horrified at what the Trump Administration is doing. Fight those fights in the courts and the media, but focus a concerted effort on educating people who voted for Trump that he's failing to bring the success they expected, and is actively doing things that will make their situations worse. A good example is the ACA. The outcry when people realized the ACA and Obamacare were the same thing, and that they were benefitting from it, and it was going away, is (in addition to being hysterically funny) a prime example of the sorts of things the opposition needs to hammer home with these folks.
Trump is taking away your health insurance (or making it 3 times as expensive), Trump is taking away your social security and/or Medicaid benefits. Trump is going to raise prices on everyday goods and reduce our profits on farm produce shipped overseas with his trade tariffs. Trump is going to kill the increased minimum wage movement. Trump is going to return the banking industry to the same state it was when they caused the mortgage crisis, the student loan crisis and the bank bailouts. Trump will cost you money and hinder your ability to move up the ladder, because the ladder is for Trump and his Wall Street friends, not for you.
This is the message that will win in 2018 and 2020.
