Point One: Bill and Hillary Clinton are victims of a perpetual right-wing smear campaign, a highly personalized subset of a decades-long, coordinated and sleazy conservative crusade to discredit government.
Point Two: Bill and Hillary Clinton evade rules and skirt laws that others are required to follow. They seek to hide conduct that should be open to scrutiny, and intentionally evade accountability. When their improper actions are exposed, they invariably dissemble. Why did Hillary Clinton use a private e-mail system to keep thousands of e-mails off of her official secretary of State account? For convenience? Please. She was dodging the rules to try to keep her communications inaccessible to the news media and Republicans. Which meant they were also inaccessible to the public and history.
Point Three: The conservative campaign against the Clintons has been so vile and relentless that they are naturally defensive. For a quarter century, dishonest partisan media and opportunistic Republican politicians have twisted every Clinton word and action — even non-action, as the fraudulent Benghazi “scandal” has made eminently clear. The mainstream news media has always allowed partisan attack dogs to set the terms of Clinton coverage. Why should the Clintons sit back and allow themselves to be torn apart? They have to protect themselves.
