Here's a New York Times oped piece against Trump that is reasoned and helpful. Of course, Hillary Clinton has put in her preparation time, but that time has only prepared her to be superb at political manipulation, lying, promoting sexual perversion and the slaughter of babies, the abandonment of fatherhood and motherhood which is her "village" and promotion of daycare—and on it goes.
In other words, if we shouldn't elect The Donald because he hasn't put in the time necessary to do the White House well, we shouldn't elect The Hillary because she has put in the time to do the White House wickedly.
