I would argue that it is a political mistake to “let the nominee just go through” for several reasons:
1. The Republicans must show that they are willing and able to fight just as hard as the Democrats on every issue. The base needs to see this and not the usual rollover, spineless act;
2. By fighting hard against the nominee, they are staking out the price to be paid for radical nominations which might make a future Democrat President show some restraint in choosing picks (fuggedabout Biden his handlers will always make the most radical picks);
3. It is worthwhile to expose the nominee’s record to the public for purposes of diminishing their reputations and making them think twice about confirming the worst charges against them in their own decisions and choices.
Pubbies have a limited amount of spine. Is this the situation to use it up on?
Also, there is some reason to believe that Breyer’s seat is going to be a lateral promotion for Harris to clear the way for Biden’s replacement. If she has to resign to go to the SCOTUS, the ‘Pubbies could hold the position of VP open negating the Dems margin in the Senate. We will have to wait and see. It might be entertaining though; Harris spectacularly unqualified for the SCOTUS.
In any case, I would like to see the the appointments qualified but, again, the amount of spine is very limited in the GOP and they are going to see Marxist after Marxist appointees with each worse than the last.
