1. He dealt with his opposition in a way that was arrogant. He paved the way for Trump to do the same. His narcissism is way over the top.. even more than Trump and that's something.
2. His bailout of the Car Companies with money soley to support union workers was fraudulent. Shareholders should have been made to suffer a bankruptcy and there would have been fresh blood to take over. GM never recovered and is still a mess. None of the money that could have been used benefited the taxpayer.. just the unions.
3. He was far too ingratiated to the banks in bailing them out.. They too should have gone bust. Too big to fail was a failure. Money given them was used to make the rich richer.
4. The Stimulus trillion dollars could have been used to rebuild our infrastructure. It wasn't. It was wasted for the most part on teacher's unions and SEIU. Much of that money ended up as pork with no good use. Now we drive on crappy roads and bridges. The economy would be far better had he left it alone.
5. Obamacare. Nuff said. Still a catastrophe. Everything he promised was a lie. Keep your doctor and $2500 total personal expense. Lies. His push for universal coverage which would be disastrous.
6. His dependence on foolish systems like food stamps to bribe the poor in society into supporting him. Obama phones and all.
7. His blatant use of government institutions to punish his enemies was criminal. The EPA and IRS among them. He turned government agencies into weapons of warfare. His justice department and the FBI using regulations to abuse his enemies was horrible. During his administration if you were a reporter that criticized him you could expect an audit, a lie detector and maybe jail. First amendment went out the window with him. Even spying on Trump at the end.
8. His divisiveness in amplifying and creating anger in racial things was one of his worst violations of human rights. Trayvon, Mike Brown and other things he used as swords to create distrust and racism among black people was over the top. He could have been a uniter but he divided us more than ever.
9. I hated the rainbow lights on the White House when homosex marriage was made law. What are we? Queer nation?
10. His international incompetence in Foreign Affairs. Syria. Iran, Iraq, ISIS, Libya, Egypt. The whole middle east became a blood bath under his watch. Worst ever.
Those are simply ten. I know that his poor choices of people, policy and programs were the core of his failed presidency.
There is a book on the market on why Obama was the worst president in History. I haven't read it or the list. But you can.
