OMG, you guys! "Idiots in the White House", "Dog whistle politics", "emotional appeals", what are you smoking? That somes up the campaign strategy of EVERY politician....EVER!!!
Oversimplification of the root cause of the nation's problems is what politicians do when they want votes. Politicians understand they need to appeal to the average person, (meaning average intelligence, education, etc.), and not necessarily the ones that can actually grasp the true and much more complex reasons for why we see some of the systemic problems we see. The easiest path to this usually is an appeal to fear. Blame the immigrants, blame an entire region of the world, etc. Hint: Illegal immigration and Islamic terrorism are not the root cause of anything. They are symptoms of a much more complex socio-economic and socio-political system that took decades to evolve. No president of any nation is going to undo that in fours years, much less through undiplomatic, impractical, Neanderthal means. There is a reason why Trump hosted a reality show, the audience he appealed to there are pretty much the same audience he is appealing to in the political arena. Very average people that are not likely to think through problems. A few of these people just actually might be a bit bigoted, because guess what, bigotry's roots lie in fear. This is the particular dog whistle frequency that Trump is playing, (pitched down just enough to be heard by a broader audience than the GOP typically appeal to).
The GOP is concerned about Trump, not primarily because they believe they will lose to him, (although that is looking probable at this point), rather more because they believe they will lose the party to him. It is correct the GOP have used the dog whistle a very long time. Trump is actually blowing their cover. That is not good news for the GOP moving forward beyond 2016, (regardless of the immediate outcome), as they have been unmasked as the backwards thinking, anti-science, anti-reason, group that they have long since become. The same people voting for Trump were former Tea Partiers, and Gingrich neocons before that. Trump is just the latest manifestation, (and his candidacy a symptom of itself), of a group of a fearful and mostly lazy people that would rather not bother to take to the time to correct the problems by looking at the big picture first.
In terms of the economic disparity we see, until the plutocracy we have in this country and abroad is brought under control, through reversal of Citizen's United, sensible tax policy, a better educated electorate, better public schools, etc., no meaningful changes are going to made. There are no short cuts, folks.
