Re: @ST The Bret thing
Not to get partisan about it, but Kavanaugh said he never drank heavily, but several of his former college classmates distinctly remember him drinking excessively, and was "belligerent and aggressive" when drunk.
That is obviously "He said"/"she said" stuff - there is never going to be "proof" of a lie, so everything has to be on balance of probabilities.
There is nothing wrong with drinking when a student, and working out how to handle your drink, but on the balance of probabilities, he fibbed about his student alcohol consumption. Personally, I'm not convinced about the sexual assault allegations, I'm absolutely convinced that as a student he got wasted regularly, and then lied about it because that would paint the assault allegations in a different light.
