We have the majority. Why try to avoid the showdown that was desperately needed to put the Dems in their place?
Because the Dems have made it clear that if they can find ANYTHING objectionable, they will beat that point until the candidate withdraws - and being an "originalist" is very objectionable to Dems.
Hence, the only option for a clean nomination is either (a) the candidate be extreme left-wing, or (b) a spotless unknown. Since the right-wing administration obviously can't go with (a), the only option is (b): a candidate that is well-known to the President ... and a total mystery to anyone else.
Put another way: she probably is a known Originalist ... known to the President, that is. So long as he knows who he is nominating, and so long as the opposition can't find anything to oppose, the right person becomes SCOTUS judge.
