Final answer:
Senate holds enable senators to block or delay a vote on a nominee or legislation temporarily.
Step-by-step explanation:
The Senate has continued to respect the practice of Senate "holds" because it enables senators to block or delay a vote on a nominee or legislation temporarily. Senate holds allow individual senators to have influence over the legislative process and exercise their constitutional duty to provide advice and consent to the president's nominees. This tradition of unlimited debate and the use of filibusters in the Senate gives senators more power to shape legislation and ensure thorough scrutiny.
