David Horowitz's book Blitz: Trump Will Smash the Left and Win is perhaps better subtitled something like Trump Will Smash the Left and, if Reasonable People Get Out and Vote, Ought to Win in 2020. Even though Horowitz doesn't quite measure up to the bluster and confidence of the title, Horowitz lays out a great case for Trump.
In sum, Horowitz reviews Trump's successes throughout his first term. He details the harsh, unfair treatment he has received from the press. He describes the many ways that elected officials, appointees, and government bureaucrats have conspired to obstruct his administration. In the face of this opposition, it really is remarkable that he has accomplished as much as he has.
If you're looking for a strong, thoroughly sourced defense of Trump's first term, Blitz is a good place to start. Let's hope, for the sake of the country, that the prediction of Horowitz's title comes true in November.
