Dean and his "issues."
Dean has been hit in the past week with things that are, frankly, ridiculous as issues. Like you point out, what problems he had 20 years ago, assuming they are no longer problems, are not relevant now.
The other dumbass thing that's been going around is an attempt to somehow link him with an employee with some spouse abuse issues or something. A quick look at it told me that this didn't stand up as any kind of reasonable hit on Dean.
Dean has enough real problems to keep me from voting for him. Why invent them?
