I had a love-hate relationship with him. The parts you are referencing made me really dislike Obama. A lot. However, I felt he was more respected on the world stage and more of a "world leader" then Trump (and I am a Trump voter). I also felt Obama had the ability to hide a lot of how he was actually feeling about issues and keep a calm, cool, collected head. I've noticed Trump seems to be able to dish it out but not take it very well. You can tell when something ticks him off. I felt Obama was able to bring communities of different people together more - legalizing gay marriage was something that needed to be done, his issues on weed were good, equal pay for women.. etc. Those things I liked. What I hated about Obama was again, what you mentioned - Obama did paint the other side in a bad light just like Trump does - he also had a very big disconnect to rural America, much like Trump has a disconnect to minorities.
And in actuality - Obama campaigned on a lot of things Trump did - even his stance on China.. Obama said all of the things Trump did.. but Obama never did them. I actually think Obama and Trump really are not very different if you look at what both campaigned on. The only difference is Trump is executing them. The Obama admin even deported the most amount of illegal aliens.. out of any president.. ever. So to Think Trump is this outlandish crazy person on the boarder really is kinda funny to me. My other problem with Obama was his constant war on the 1% - yet he could have punished a lot of those 1%'ers after they literally crashed the entire economy and I think Obama only sent one big banker to jail, and compared to the rest of the bankers.. this guy wasnt even that big of a deal... but someone had to go down and they chose this bottom of the barrel dude that took all of the blame.
