I believe you are spot on with that assessment. I had watched in dismay as my wife, an otherwise intelligent and well educated woman, fell lock stock and barrel for all the emotional rhetoric
having no logical foundation during this past 2016 election. She had been reading all the rogue fake-news/alternate-fact websites and did absolutely no fact checking of anything they said, because that fact-checked answer would be contrary to what she wanted to believe. She listened to all the emotions and then closed her mind to any other possibility, and even stopped watching the nightly news that was more or less balanced reporting. Admittedly several stations were not very balanced, but then any publicity tended to be good publicity if you could prove you really didn't care what others thought about you and instead stuck to the emotions rather than facts or actual proposal of plans. The more indeterminate you were, with your expression of your intent, to put a plan together, the more the public at large liked the plan.
The bottom line is emotion won over any level or fact and reason. Nearly all the emotionally delivered [non-]promises were either impossible to implement (financially, politically, or even based on actual physics) or were not even founded upon documented facts, but rather just ill conceived partial thoughts, pulled from an 'A', far away in some alternate universe. No amount of logic or reason can prevail when someone becomes so emotionally entwined as to deny the simple fact that reality, as a thing, might possibly exist somewhere on this planet.
Step right up. Get your "super big" "completely impregnable" wall here, and we will solve all your problems! Never mind that man behind the curtain! [e.g. If you do get the wall as promised by the opulent snake-oil salesman, you also get the shaft. You are definitely paying for it, every penny, in the form of higher prices, not the Mexicans. One would think a Billionaire would understand simple economics. As an extra "free-be" we can throw in a little something to make that deal even sweeter, "all the US wildlife on this side of the river get to die of thirst, without the ability to get to the river". Ding, Ding, Ding! Give that little girl a dolly! Under this current "plan" we also stand to save lots of money on wildlife restoration programs, because there might not be anything left to save in the arid desert regions. Meanwhile the Mexicans just continue to climb over the existing wall, digging tunnels under it, or possibly shift to spending their normal smuggler handling fee instead on a standby airplane ticket for a "fun-packed-vacation" to the US, and just burn the passport/evidence and forget to go home. One positive benefit of the wall building project will likely be lots of on the job training for the Mexicans, who will likely be hired at minimum wage (or below) to actually build it.]
