Why I will vote for Donald Trump

I have written here and elsewhere about my misgivings over Donald Trump. In particular, I co-wrote a study that was sharply critical of his ideas on trade policy. I have cringed at Trump's off-the-cuff personal attacks on people. He was my last choice among the initial contenders for the Republican nomination. He has run a terrible presidential campaign. Yet, I am going to vote for him in the presidential election.
The principal reason is that I fear for the country if Hillary Clinton is elected. Hillary Clinton does not just want to be president. She also wants to further a radical movement, for which both she and Barack Obama are 21st century torch bearers. Obama is a protégé of the communist Frank Marshall Davis, the terrorist William Ayres and the black liberationist Jeremiah Wright. Both Obama and Clinton were heavily influenced by the neo Marxist Saul Alinskly, whose core strategy was to use any means necessary to bring down business and government institutions for the benefit of what he deemed to be the disadvantaged.
