The FBI follow-up investigation was a sham. No one of substance was interviewed; material information was offered, but not followed up; the American people were not allowed to even hear the results, with precautions taken to ensure they did not hear it.
The Kavanaugh FBI Investigation Was a Sham: Report
The Cons decided to run their con-job on the American people jamming through an unpopular, highly suspect candidate.

Harry Reid is not responsible for the Kavanaugh. He changed the rules for OTHER federal appointments, largely because the Cons were gumming up the process, not allowing political appointments to happen. He did not advocate an adjustment for SCOTUS nominees. That is entirely the Cons doing. Don't try to sell you conjob here that Harry Reid has anything to do with this.
Jamming through a judge that the American people do not want in the SCOTUS is an arrogant and dangerous form of politics. Our democracy took a major hit by the reckless actions of the minority of Americans here. Trying to govern a democracy from the minority is not a winning long-term formula for a party or for the country.
See what the Financial Times (the Wall Street Journal of the UK) has to say about this...

The truth can only be buried for so long. It is just a matter of time (and maybe some congressional investigation) before we learn what was short-cutted and the real truth about Kavanaugh. In the interim, the taint of doubt on Kavanaugh remains as fewer people believed him than Dr. Ford.

In the short-run, his credibility has been tarnished and, by extension, so has the credibility of the SCOTUS. Damage has been done here.
