Any sane person can see Trump doesn't really believe anything he is saying. He no longer puts the good of the country at the heart of the race, even on a pretend basis. Ideology no longer has anything to do with it. Now it's just a straight personality cult.
The fact that he is at the center of the GOP stage shows that it is no longer a political party at all, just a collection of disgruntled people who are willing to back anyone in order to take away rights they feel should be denied to anyone that isn't a white, middle/lower-middle class, FoxNews watching American.
