Donald J. Trump was (and is) an unmitigated disaster of epic proportions. He literally did NOTHING to advance our country in the right direction and, in fact, wound back the clock on virtually every important facet in our nation including health care, civil rights, trade, the environment, and our standing in the world. He's an opportunist of the worst kind, and sought to advance his own personal well-being and financial interests, while sewing discontent and conspiracy theories with his fans.
His elevation to the highest position in the nation was a complete fluke and the result of disenfranchisement and anger he stoked for the benefit of one Donald J. Trump.
He'll go down in the record books (and in flames) as the worst President in modern history, and may in time lead to the end of the GOP altogether.
