How do presidents use their appointment power to exercise control and increase their status?

What will be an ideal response?

An ideal response will:
1, Note that the president can reward loyalists with appointments in order to increase their loyalty.
2, Describe how the president can use appointments to staff the bureaucracy with people who will vigorously enforce the president's policies and fail to enforce, or enforce weakly, the policies with which the president disagrees.
3, Mention that presidents can use appointments to increase diversity in government as a means of pleasing their constituencies and attracting more voters.
4, Identify that presidents can demonstrate bipartisanship by appointing some people from the opposite political party to their cabinets.
