Seems to me that it is wrong for the Congress to create offices that require commissions granted by presidential nomination and the advice and consent of the Senate, but then have the Senate not vote on the nominees. Especially when it is close to certain that many of the nominess would be confirmed by a majority of the Senators.
This case seems like a giant waste of time created by another giant waste of time.
IMO, I could see there being some senatorial courtesies regarding federal judicial nominees for the senators from the state(s) that federal court would have jurisdcition over, but nearly all judge nominees should get an up or down vote.
Not giving up or down votes on nominees for the NLRB and any other Congress created agency requiring a Senate confirmation seems to me contrary to what the Framers expected when drafting that section. Seems to me wrong that offices remain vacant when the POTUS nominates someone that would be confirmed on a floor vote.
