It pains me to point this out, but I think some people are mad at him for not doing enough. I have to believe that some of the low ratings are due to him not being Trump enough. I am pretty sure there are a bunch that are pissed the ACA hasn't been scrapped yet. Yeah... They also probably want him to outlaw Muslims and probably tell gay people to stop being so fabulous. Also, they probably want to make it illegal to point out their bigotry or to call them hateful.
I am pretty sure those people exist. I apologize on behalf of America and ask that you not blame me. ;-)
I will give Trump supporters some credit, because many of them became genuinely disillusioned after Trump's continuation of the status quo foreign policy in the Middle East and after the Saudi arms deal. Hard-line Obama supporters are easily as racist as Trump supporters, why else would they go mute for 8 years while hundreds of thousands of Muslims are murdered by their candidate?
