Answer:
Conservative.
Explanation:
The term 'conservative' is used to denote 'someone who usually supports or favors the maintenance of status quo' and denies any kind of change or modification in the conventional institutions or beliefs. These people usually tend to show support, in fact rigidity to the 'social as well as economic status quo' and tend to show an opposition towards the introduction of any kind of new political arrangements or economic formulas that they view as a threat to their existing authority of beliefs/status quo. Therefore, such a person would be considered as 'conservative' in present context.
"that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or abolish it." John Locke believed that the government should bend to the people. This is why we have the first amendment, it says that we can protest our government if they do not follow the standards of Life, Liberty, and the pursuit of happiness.
What do you want to compare exactly?
The Chief of Staff.
All of the advisers listed in your question have important roles to play, but the White House Chief of Staff is continually in contact with the President, and so would be the one more likely to have insight into the personal thoughts of the president. The Chief of Staff controls the flow of other persons into the Oval Office for time with the President. The Chief of Staff also serves as an adviser to the President and a negotiator for him with other members of the government. The Chief of Staff is the person most often at the President's side. Also, whereas Cabinet officials and the National Security Adviser advise the President on issues specific to their appointed roles, the Chief of Staff is involved in the President's planning and communication in regard to all issues of the administration.
