4 good reasons to conclude that Hillary is a crook:
1. Subpoenaed Whitewater billing records that were "lost" until they magically appeared years later sitting in plain view in the White House.
2. Blatant violation of national security regulations by setting up her own server to control access to her correspondence from her time serving as Secretary of State.
3. The Clinton Foundation where foreign donors go to buy influence in our government.
4. Libya/Benghazi. The lies told to the public and the families of the victims about the cause of the attack. You can throw in total incompetence and dereliction of duty on that one to boot.
