In some cases they may not be seeing it. But even if they do see it, they work off a preconception that everything he does is correct, and that everything that the media or democrats say about his conduct is automatically untrue. If they do not understand Trump's actions, they just assume he is playing 5 dimensional chess. You know, because the God Emperor acts in strange and mysterious ways only understood by the God Emperor himself.
Short version: they don't give a crap what he does so long as he "pwns the libs" while he does it.
I will add that many have been brain washed by Fox News and friends (ION, Newsmax, etc). I have many family members who support Trump, and when ever I show them the truth, the actual facts, they call it fake news. They have been programmed to believe the lies as truth, and the truth as lies. We are headed down, or I should say, we have been heading down a very dangerous road because of this.
Trump is not the person we should be worried about. It's the next guy, or Trump 2.0, who not only has the Dangerous, criminal characteristics of Trump, but also brains and the ability to speak. If Trump 2.0 has all of Trump's Evil Character, combined with Obama's Charisma and Brains (ability to speak in a smart manner), we are truly fucked.
