There are many factors, the biggest of course is fear. Fear of job loss, others getting more than you, the race factor.
trump did not come full blown on the scene, it's been building, nurtured by big corporate and the rich.
People in this country and around the world are really starting to piss me off.
I'm with you - how do they NOT SEE this agolf twitler for who he is.

I can answer your question assuming it is not rhetorical. I went into their domain to try & understand just how they could support such an un American traitor. The answer is cult. They follow instead of thinking for themselves. Cultists follow the leader as lemmings right over the edge. Nothing matters but the leader & his edicts. The leader tells them what they want or need to hear & they follow the leader of the cult into the abyss. Facts do not matter. Feelings do. They FEEL he is correct. They agree with the leader's assessment. What I heard & learned is frightening. I am in fear for my country.

BLIND faith...just like the godbots...facts are the enemy

The blue collar worker is getting killed by him. He is attacking Social Security, unions,health insurance, working benefits and they still are supporting him?He opposes OSHA and the CDC which offer protection against work related conditions.He is raping the other 90% of the people with the wealthy tax cut. He wants to take away the protection of the Constitution and modify it so they have even more power.

I don't either. It is scary that this is happening.

It's a combination of things...

1. Cognitive dissonance. People will hear what they want rather than what's actually being said...
2. Lack of education. There's a saying about those that don't know history, and it applies in spades here, and/or...
3. They genuinely have something to gain. While this of course doesn't apply to the majority of his supporters, there is of course a powerful minority that stands to gain from his consolidation of power.
   Dictators don't dictate from within a vacuum. They are propped up by powerful factions. A physically powerful military, an economically powerful oligarchy, a morally (I use the term academically) powerful religious sect. It works to the benefit of those factions to not, themselves, occupy the seat of power, but to prop up the dictator that does in that the smart dictator knows from where flows his power. Concessions and liberties are given to supporters to keep them supporting, with the most generous of course going to the most powerful. The majority of the base, you can satisfy with empty promises and flowery rhetoric, at least in the short term. Your elite backers however, must be given tangibles commensurate with their support, else the dictator finds that the pillar of support that he thought was made of missiles, money, and moral authority was made of mist. (You like that alliteration? Lol)
   Secondly though, in the event that the throne were to be toppled, the dictator is almost certainly finished, but there is at least a slightly better chance for supporters to step clear of the fallout, even to possibly attach themselves to the next person to fill the power void.
   Not everyone has it wrong. Some (more than a few I'd argue) know exactly who and what they're backing.
