Trump is far enough to compare to Obama. I think Trump is better than Obama even if his behaviors is not good on foreign relations. But he always act quickly and very fast on making solution. Unlike Obama, he is just watching problems and very busy for implementing law that not needed of the USA just like same sex marriage. He is the worst President of the USA for me.
If you believe the rating is Obama one of best presidents of America, and Trump one of the worst. I do not support Obama for his weakness. He really took no decisive action, and when it America has lost its image as a world leader, but all his decisions were deliberate and measured. What can be said about Trump. Trump decides not the mind and emotions. It is good in business but not in politics.
