It is hard and unwise from this side of the Atlantic to try and call American elections, but it is becoming obvious that Trump now has momentum which may not be stoppable. He narrowly lost Iowa but has won comfortably everywhere else. Indeed the margin is going up. In Nevada he polled twice the votes of the next man, Rubio. The question now to be pondered is not what will happen if Trump gets the nomination, but what happens if he becomes President? Quite a lot probably.
