I have a hard time believing the same country voted for both Obama and Trump to be their leader.
I don’t think this is hard to believe -for Obama the Democrats came out of the woodwork to vote, and for Trump the real Americans came out of the woodwork to vote. 
Me too. Schizophrenic. One extreme to the other. Undereducated voting public, lacking in critical thinking skills. A continuing pattern.
Their experience of Obama prompted them to choose Trump. Not complicated.
Go look up some of Obama's early speeches about immigration. Then listen to some of Hillary Clinton's early speeches when she was in the Senate and Bill Clinton's early speeches about immigration when he was president. All of them were saying illegal immigrants have to go they have to go back to their home countries and start over at the end of the line. I know you're not going to believe me so just go look it up.
