Trump was a democrat before he decided to run as a republican. He has said so himself and has contributed more to democrats, including hilary. Just something to think about.
He is not a conservative and was naturally aligned with Democrats before, but only as status quo business affiliation relationship rather then politically.
But he is first and foremost a completely retarded case of extreme populism. He will say whatever it takes to further his cause of getting elected / getting the center stage. He just wants to dominate the rhetoric and tap into the disgruntled voices, which are full of fear and hate, which makes ideal for a vulture like him, play up patriotism and it's all the foreigners and alien enemy religions fault, I doubt he means most of it.
But deep down he must mean some of it because it comes easy to him, and also he has over two decades as a businessman of making dumb insulting comments about Jews, Mexicans, blacks and women. So small winded stereotyping and bigotry comes easy to him it seems. Doubt it's enough to govern him as an individual or politically, but enough to see it as viable tactic to dupe the right wing extremists to vote for him. Sheer populism.
That's why I disagree with Seven he is as bad as Le Pen, Geert Wilders or the other genuine right wing extremists leaders that are clear proud bigots. Difference is America right now is bit more crazy and offers opportunity to Trump that he would never get on most main European nations. Except for Italy, Trump = Berlusconi...
