What the politically connected/insiders/ are having a difficult time with is the fact that the people like and trust this man. That is what is fueling his campaign. As long as the people continue to do that...they will not be able to deflect or stop him.
Despite inexperience as a politician (which many of us count as a positive), people know he has been very successful as a hands on businessman with large companies. They also know he is plain spoken and a moral man, as in traditional morals. They trust him to get in there and use those qualities to solve problems for Americans.
Again, as long as enough of us retain that trust...they will not be able to stop him.
