To win the Republican nomination you need to be a very right wing. The Republican base who vote in primaries tend to be very right wing. The influence of the Tea Party has exacerbated this situation. So Donald Trump is doing very well in the GOP (“Grand Ol’ Party” = Republican party) polls for the 2016 Presidential nomination. The more he says that Muslims need to be tracked on a database, the border needs to be closed to them and a border wall needs to be built by Mexico, the more the Republican core adore him.
I’ve lost count of the number of times commentators have expected a “Howard Dean moment” to befall Trump. It’s not going to happen. He’s like Boris Johnson. The more he makes embarrassing comments, the more a certain constituency of people love him. He can talk himself out of any corner. – Even if he uses the verbal equivalent of a 12 bore shotgun.
