Why can't the Republic-a-ons just nominate some other conservative blowhard?

Seriously. At this point isn’t it better to just nominate someone who won’t be a stain on the Supreme Court? His behavior at the hearing, his lies (not even talking about the accusations), his evasive behavior and refusal to answer questions, his blatant partisanship and spouting of conspiracies makes him unfit for the appointment. Why this guy? What’s so special about him?

Theories?
