Holding rank-and-file judicial nominees hostage to advance a larger political agenda is the current political "nuclear option" and, if this continues, it is the judiciary and Americans seeking justice who will bear the fallout.
Can you imagine a trial in which the judge commenced the proceedings by announcing their verdicts and then calling for the submission of evidence? The Senate hearing on a judicial nominee is not a trial, but it certainly is akin to one.
So Senator Cornyn's attack is based on...what? Because Johnsen repudiated the Bush administration's legal opinions, that proves she lacks "requisite seriousness."
