Yeah that may be true but the choice should never, ever, be up to a politician to decide. Do you removed the lost email from the bush admin? Did you blow that off? There is no reason why someone who controls their emails couldn't "lose" important emails that at be embarrassing or detrimental to them. Why even tempt someone with that power?
I doubt clinton did anything wrong but if you excuse her behavior then you are excusing future behavior and the next time it happens it may not be someone on "your" team.
She played by the rules. So did the Bushistas. Neither committed any crime. Well, not wrt email, anyway.
And, remember, imitation is the sincerest form of flattery.
