Pretty neat trick - define the relevant population (two people out of dozens of cabinet level WH officials) so you can exclude the White House email scandal of the latter Bush years and MILLIONS of deleted emails. That's relevant, sorry, especially when you're recommending a JAIL term for Hillary over this. That's fine, and we can jail her in the same cell block as Karl Rove and the rest of the Bush WH.
Besides, as you can tell from what you quoted, I'm conceding wrongdoing on Hillary's part, including that IMO she clearly used a private email server to effectively manage what does and doesn't get released - or delete any that might prove damaging if you prefer. That's relevant and highly damaging. The only thing I get a little tired of is the fact that it's a Clinton involved, so if there's a problem she ought to be arrested, tried, convicted and JAILED!!!! Give me a break. The only people buying that are still worried about BENGHAZI!!!!
Sorry Jasper, the reason for focusing on your Powell red herring is because AT LEAST that sounds related. The so-called "Bush staff e-Mail scandal" is even less related. But as you insist:
First, Hillary Clinton is "the only secretary of state known to have conducted all official unclassified government business on a private email address." Years earlier, when emailing was not the ubiquitous practice it is now among high officials, White House staff used both government and private accounts, one for official business and the other for political, personal, and other business... as effectively required under the Hatch Act. And it's a striking departure from the norm for top officials to rely exclusively on private email for official business.".
Second, White House staff did not, as far as known, generally use the private email for government business. While there may have been many exceptions, the primary purpose of the system was not to conceal official business - which was the ONLY real purpose of Clinton's system. There may have been violations by Bush staffers of the Presidential record act but that is uncertain.
Third, if Hillary had a separate email address for personal, political, or other business (as did the white house staff)...on a private server, and had used her State Department email address only for business there would be no controversy. If she deleted her pwn account emails from her server, there would be very little controversy. BUT she blatantly set up a system to hide her motives and actions.
Four, in 2009, the year Clinton became secretary, federal regulations codified that a contemporary transfer to archives is required of personal e-mails used for official business. She did not do so, intentionally.
One has to measure the actions by the standards, assumptions, laws and intentions of the respective persons at the time of their service.
