Yes, more low blows are coming. But it does matter, because we don't have a functioning free press.
The news story is not "but her emails" or "but his memory." The story is that a DOJ special counsel abused the power of his office, and broke the law, to turn his official report into a partisan smear.
The GOP will continue to flood the zone with bullshit. If the press continues to collect and amplify that bullshit, our democracy has no hope of survival.
