Nope. Not even close. Our first nationalist, "tribal," "cultish" president was George Washington. Barack was our first Saul Alinsky/Marxist inspired European Socialist president, and, hopefully, the last.
To reiterate, we have elected 43 nationalist presidents before Obama and Trump. That's an unadulterated fact of life. And now, we are in the process of repairing our nation after the disastrous eight year presidency of our first wannabe Muslim president . . . . a man who had never even managed a fruit stand. He had no qualifications as a Commander and Chief, as a financial guru, as an economist, nor as a world leader. He had a law degree which he strangely abandoned after winning the presidency, and, is our first presidential "scholar" without a published, peer-reviewed paper. In fact, the only writings he has ever published are two auto-biographies! What does that tell you about our 44th President?
As to his legacy, after eight years, his Democrat Party has been left smoldering in ruins, and, at its political weakest since Reconstruction (1865). Worse yet, the Democrat Party is without a leader.
Now you know.
