The woman who said she lied was not one of the three who'd come forward before Kavanaugh's confirmation
She was someone who wrote an anonymous letter and later claimed she lied.
Her dishonesty does not reflect on the honesty of Dr. Ford, Debra Ramirez, or Avenatti's client. She had nothing to do with them.
Nor does Kavanaugh's confirmation reflect on the honesty or dishonesty of those accusers. The FBI was not allowed to do a sufficient investigation, and only 7% of Kavanaugh's papers were shared with the Senate before the vote.
Truthfully, I believe that the Republicans who voted for Kavanaugh's confirmation would have done so no matter what evidence had been found against him. Similarly, the Democrats would have voted against Kavanaugh because of his judicial philosophy, even if there was sufficient evidence to authoritatively declare him innocent.
