They can always reinstate them if the Democrats ever take the Senate.
Currently, there is no need for them. The Senate only has to “advise and consent.” There is no requirement for hearings. The fact of the matter is hearings only serve to damage the nominees and allow Democrats to prance and preen. It helps no one except Democrats. Every nominee should be brought to an immediate floor vote and just disallow Democrats to take part in the process beyond a vote. This has become ridiculous.
