Does it really matter that the R's confirmed her twice previously? Wouldn't the SCOTUS be considered a promotion from level she is at now? So is it possible she is qualified for the level she is at now, but not for the next?
Just asking the question, as I know nothing about her or her background, or what kind of qualifications it takes to become a judge. I do know though that just because you were promoted or selected for advancement in the past does not guarantee promotion or advancement in the future.
