For those that read at or below a 6th grade reading level:
“The Senate’s ability to say yes or no to the president’s chosen leaders helps stop unqualified people from getting these important jobs. This includes stopping people who would only be picked because they’re unimportant enough to just do whatever the president wants.”
For serious people who can read the big, original words from the American Enlightenment, this is Alexander Hamilton in No. 76 of the Federalist Papers, which was a propaganda campaign advocating for ratification of the Constitution:
“The Senate’s power to approve or reject a president’s top nominees would tend greatly to prevent the appointment of unfit characters, including those who had no merit other than that of possessing the necessary insignificance and pliancy to render them obsequious instruments of the president’s pleasure.”
The essays are considered a seminal work in American political philosophy and constitutional interpretation.
