Ask any casual observer what the Brett Kavanaugh Supreme Court confirmation fight is about, and the answer will be the allegation that at a high-school party 36 years ago, when Kavanaugh was 17, he drunkenly forced then-15-year-old Christine Ford onto a bed, tried to undress her, and, when she tried to scream, covered her mouth with his hand.

That is now old news. In the last 48 hours, immediately after Senate Republicans and President Trump agreed to Democratic demands that the FBI investigate the 1982 incident, the Kavanaugh goalposts have moved dramatically. Now, a key issue is Kavanaugh’s teenage drinking, and whether he testified truthfully to Congress about the amount of beer he consumed in high school and college more than three decades ago, and the effect it had on him.
