I'm going for his lack of credibility. All he had to say is yeah, I drank underage and give some sheepish apology or wish that he hadn't. I doubt anyone would hold that against him. Instead he lied about it. Why? The only people I know that lie over small things like that are compulsive liars. It's like if a grown man said he never fapped once in his life. You'd think what bullshit, why would you lie about something pretty much everyone did? And if I can't trust you to tell me the truth over little things I'm not gonna trust much, if anything, that comes out of your mouth. And I don't feel someone like that belongs in that position.
