Final answer:
A president usually has an easier time getting nominees at the District and Circuit levels compared to the Supreme Court level.
Step-by-step explanation:
The process of getting nominees at the Supreme Court level and the District and Circuit levels can vary, but generally, a president has an easier time getting nominees at the District and Circuit levels.
When a vacancy occurs in a lower federal court, the president consults with that state's U.S. senators before making a nomination. Through senatorial courtesy, senators exert considerable influence on the selection of judges in their state. This means that a senator can block a proposed nominee just by voicing opposition, making it harder for a president to get their nominee confirmed.
On the other hand, when it comes to the Supreme Court, the president's nominee is discussed and debated in the Senate Judiciary Committee, and then must be confirmed by a majority vote of the full Senate. This process can be more contentious and politicized, especially when there is a divided Senate or significant ideological differences between the president and the senators.
