The “investigation” was directed by the individual assigned to get Kavanaugh confirmed, and was designed to deliver no significant results. But Kavanaugh already had a history of perjury and extreme partisan activism, and further demonstrated emotional immaturity that should automatically disqualify him from a lifetime appointment to the Supreme Court.
In other words, it should never have come to this sham investigation. He’s a terrible candidate, and it speaks volumes of the corruption, bad faith, and general debasement of today’s GOP that they would promote him.
There are plenty of qualified judges who would interpret law in a sufficiently “right” way (see Gorsuch, Neill), that are otherwise fit to serve. There is no excuse for pushing Kavanaugh, none; no matter where you are on the political spectrum, this is just plain bad - and bad-faith - governance. It’s also shortsighted; if they confirm him, he will be damaged goods and simply drive ever-greater opposition to their agenda and candidates.
