Matthew Yglesias cuts to the heart of why I could not give two farts about the email "scandal".

The formative experience of my political life was the 2000 presidential campaign, in which the media mercilessly persecuted Al Gore over a series of trivial exaggerations and now-forgotten pseudo-scandals while giving George W. Bush a pass on the fact that the central premises of his economic agenda were lies.

We can include the Clinton impeachment in this, too.  Or Whitewater.

What Hillary Clinton did was legal and done by several other people who have held Cabinet posts.  But it's a "style" issue rather than a policy issue.  And most media doesn't do policy because most Americans can't understand policy.

Lather, rinse, repeat.
