I could go as far as smug and even conceited, but I’d be interested to know what actions of his demonstrate his craziness and hatefulness to you.
I agree with Jay here. Obama does seem smug, condescending, and arrogant, but he’s certainly not crazy and I can’t imagine who he could be construed as being hateful towards. He’s certainly done a lot of bad or neglectful things during his presidency, but these seem like unfair accusations to me.
Trump on the other hand is pretty much all of the bad things people say about him. While he will unfortunately have the ability to screw all of us over in so many ways (some people much more than others), thankfully his powers are limited.
