Republicans love to complain about bias in the media. The press have covered for powerful Democrats for generations. If President Richard Nixon had been a Democrat, he almost certainly would have avoided impeachment and resignation, and if a Democrat ended the Cold War without firing a single shot, well, he’d probably be on Mount Rushmore.

The constant talk of media hypocrisy now rings hollow, but not because the media have become more balanced in their coverage over the years. In fact, they have become even worse. Corporate journalists no longer simply run interference for Democratic politicians. They now essentially do the campaigning for them.
