Actually, Anonymous, the hacker group that the hackers are being labelled as "affiliated with"... isn't political in nature.
Also, yes it does make it different, and until those aspiring senators actually run for pres., they should keep their privacy. But once they enter the race and are a serious contender (we're not talking about green party candidates here... everyone knows they have no chance), the only things about them that the people shouldn't know, is what they look like naked, and what they do with their spouse while naked. Everything else, from their health, to their finances, to their diary, should be made available to the public.
PS - I'm going to give up at this point, as it doesn't seem to be going anywhere, but I will leave you with this thought: The government reads your private emails, why shouldn't you read theirs?
