How do you know it’s ridiculous? You personally know his habits. I sure don’t? I only asked if it was a possibility.
I imagine a rather thorough medical history and physical exam are part of being considered for some of the positions Kavanaugh has held. You can be sure that laws and rules about medical confidentiality would be thrown out the window if some die hard liberal who had access to such records thought evidence of a serious drinking problem had shown up at some time.
You don’t go unscathed if you have been a heavy drinker for 30+ years. The toll it takes on the body is multiple and gets more and more obvious not just to doctors but to family and friends too. Also the habit of lying that is so much part of the drinking gets easier for others to spot. One sign is that stories keep changing. With the drinker insisting that each version is the true one. It is so ingrained that heavy drinkers will lie when there isn’t any reason to. Kavanaugh struck me as being very open and honest without any attempts to manipulate those taking his testimony at the hearing.
