What Mr Trump "says" on a personal level is unimportant, As Lighter says he is playing a game.

As far as politics are concerned IMO, the breaking of the corrupt two party system is what is important and the only way that can be achieved is by a populist like Trump, who will not be controlled by the political establishment.

The present polarisation of American party politics is also just as much of a game as the one Mr Trumps is playing, the establishment having fooled people into the belief that there is any real difference between the parties.
Both are in place to serve themselves and global capitalism, not the electorate.
