Honestly, why would you even run in the first place if you've done anything even remotely questionable.
Yeah, nobody wants any more incredibly groomed dweebs whose families have been prepping them for office since middle school, but come on.
How dumb are people that they assume they'll be able to get away with anything more serious than shoplifting gum once as a child when they're subject to the most scrutiny anyone could reasonably expect to see in their life? You're invariably going to have like 10,000 journalists digging for any scoop they can find on you, and they're not going to leave any stone unturned.
