What Trump really is is the conservative right's creation due to their hate of Barack Obama.
Trump being the opportnitist and business man he is swooped in on the opportunity to capitalize on this; however, Trump's views do not really align with the most of grassroots Republican viewpoints and they now find themselves in a pickle.
