MEGAN MCARDLE: Why You Should Care About Hillary’s Email:

What can Hillary Clinton have been thinking? On January 13, 2009, she — or, more likely, someone on her staff — registered a new domain: clintonemail.com. And for her entire term as secretary of state, she would use private e-mail instead of government accounts for all her electronic correspondence. She never even got a government e-mail address, which must have taken some doing, because in most organizations, those e-mail accounts are created before the new employee even arrives.

As Politico points out, keeping Clinton’s e-mails off government servers means that they were invisible to Freedom of Information Act requests about her communications with anyone outside the State Department. Her staff has turned over e-mails from the private account, but this is not the sort of job that should be performed by someone personally employed by Hillary Clinton. Decisions about what to turn over and what to keep private should be made by career government lawyers whose job comes from the agency, not Hillary Clinton.

It’s difficult to avoid the conclusion that this was an attempt to avoid transparency and accountability for whatever it is she wrote. Such manipulations should severely hurt her presidential aspirations. Odds are, however, that Democrats will rally around her, because what choice do they have?

After all, power for the Party is more important than, well, anything. Plus:

That’s bad news for the country. It’s bad enough that our last two presidents developed a penchant for secrecy and executive overreach once they got their hands on the reins of power. But if Hillary Clinton starts at “flagrantly breaking transparency rules,” where can we expect her to end up?

Where, indeed?
