The more he feuds with career-politicians and the media, the higher his numbers will go. Generally speaking, the republican base is very tired of political correctness and the dishonesty and tactics of corporate media. Even if Trump has no concrete plans, the fact that he is not politically correct and that the media is trying very hard to discredit him is what is pushing his #s up. I think he will be the nominee as the rest are all career politicians and career politicians have lost the last 2 elections to democrats.
zogt_besser, I think the reason Donald is doing well is because most people believe the opposite. Being polite to those who insult you is not a characteristic of a strong leader. It is a characteristic of the current leadership and the GOP voters seem to want a hard-line negotiator type that won’t take insults or be pushed around easily.
